8d0dd0d1c1 Add support for pack/unpackUnorm2x16 to public SkSL.
This includes compile-time optimization and tests.

The unit test is disabled in a followup CL
(http://review.skia.org/447057) because it exposes a Radeon 5300M bug
in OpenGL.

b6981fb6a4 Add float-packing intrinsics from sksl_gpu to Metal.
It turned out that Metal had equivalent intrinsics/casts all along; we
just needed to emit them.

Tests will be improved in a followup CL which adds the ES3-compatible
packing intrinsics into sksl_public.

14c3175d7a Add ES3 intrinsic modf to sksl_public.
The test has been improved and now covers a variety of values. Because
this intrinsic has side-effects (an out-param), we do not support
optimizing it or treating it as a constant-expression.

The modf documentation doesn't mention anything about constant-
expression support or lack thereof. Experimentally, modf is also not
treated as a constant-expression by Apple GLSL or glslang:

201b72a7f4 In runtime effects, treat all children as sampled
An unused child that used its coordinates would triggers asserts in the
GP - we expect that all FPs are sampled/invoked. This generates slightly
sub-optimal code (we compute and interpolate the local coordinates for
that child FP), but it's not likely to happen in real code.

ff6c5bf5ed Generate more diagnostics from IRGenerator, when given bad code.
Two minor changes:
- Converting a Block with bad statements will now generate a partial
  block instead of nullptr.

The change mirrors how DSL behaves; functions containing invalid
statements will now be created and added to the program. Previously, we
would discard a function definition with any invalid statements inside;
this prevented duplicate-function-definition errors from appearing.

- Converting a return with a bad expression will now generate a
  poisoned return instead of nullptr.

This change improves diagnostics for functions with invalid return
statements. If we eliminate the return statements (by returning null),
we report bad return statements as "function can exit without returning
a value" (which is confusing).

733fd74c29 Improve unit testing of for-loops.
An ES2-compatible for loop supports six separate rel-ops:
   < <= > >= != ==
Each rel-op, in addition to its expected usage, is also able to
represent a loop which never terminates, as well as a loop which
terminates instantly. Since SkVM unrolls these loops, we should make
sure we do it properly. We now have unit tests for all of these cases.

3ff77f4862 Fix inliner bug discovered by fuzzer.
Intrinsic-call optimization can be triggered during inlining. In this
case, inlining turned `normalize(x)` into `normalize(constant-value)`.

DSL is used to implement optimizations for a handful of intrinsic calls,
including `normalize`, which internally relies on `length`.

The DSL expects that it can use the IRGenerator to handle function
calls. This was not working because we were finished with the initial
compilation pass, and the IRGenerator's symbol table is removed when
finish() was called.

We now temporarily give a symbol table back to the IRGenerator while
the inliner runs. We remove it again as soon as inlining is complete.

7deee71593 Remove recursion from SkVM dead-code elimination.
Previously, deeply-nested loops could lead to stack overflow during SkVM
dead-code elimination. The DCE algorithm in SkVM now stores its worklist
on the heap and does not rely on recursion. Since we now enforce an
upper bound on maximum program size within SkSL, this worklist's size
should always be reasonable and bounded.

2af4b13925 Reject programs which exceed 50 stack frames during size analysis.
Our program-size analysis pass needs to recurse into called functions;
depending on the exact order of functions in the program, this recursion
can hypothetically be as deep as the deepest function-call chain. Set an
upper bound on recursion here, so we don't overflow the stack while
trying to check the program size. In practice, 50 frames is far deeper
than a regular shader should ever go.

61e5e202a5 Enforce an upper bound on Runtime Effect program size.
The fuzzer is currently learning to make unboundedly-large programs by
nesting medium-size loops repeatedly. SkVM doesn't have a mechanism to
limit the ensuing explosion of code and ends up making unreasonably deep
stacks and/or unreasonably large programs.

SkSL now enforces an upper bound of approximately 100,000 IR nodes on a
fully-flattened, fully-inlined strict-ES2 program. The limit is picked
out of thin air, but this should be enough to prevent SkVM from going
haywire while still being large enough to handle any reasonable program.
We can definitely tune this value if we find that it is too large
(admitting dangerous code) or too small (rejecting good code).

2ecc595e86 Migrate program finalization logic out of IRGenerator.
Most of the logic in IRGenerator::finish has moved to
Compiler::finalize. The @if/@switch pass has been combined with the pass
that verifies no dangling FunctionReference/TypeReference expressions,
saving one walk through the IR tree. Most program-finalization logic now
exists in Compiler and Analysis.

This change reorders our error generation logic slightly, and manages to
squeeze a few extra (valid) errors out of one of our fuzzer-generated
tests, but is not really intended to affect results in any significant
way.

5cec187b36 Fix array timeout discovered by the fuzzer.
The fuzzer discovered that, when we attempt to verify that an array
doesn't contain any literal values that are out-of-range for its base
type, we pay a linear-time cost based on the size of the array. This
happens even when the array value isn't known at compile time; we still
iterate over its slot count and diligently discover that every single
constant-subexpression slot in the expression is "null".

We now have a helper function on Expression,
`allowsConstantSubexpressions`, which only returns true for expression
kinds that can contain constant subexpressions. We use this helper to
skip over this linear-per-subexpression check when the expression
cannot possibly contain a constant subexpression. In particular,
`AnyConstructor::compareConstant` and `Type::checkForOutOfRangeLiteral`
will now early-out for expressions that can't possibly contain a
constant subexpression.

f89a8122a4 Fix flaws in minus-prefix optimization.
We had a logic bug when attempting to optimize the following code:
    const vecN x = vecN(a, b, c);
    -x;

The goal was to replace `-x` with `vecN(-a, -b, -c)` but we accidentally
tried to cast the `x` VariableReference to a Constructor. We
unfortunately didn't cover this in any of our test cases, but the fuzzer
managed to synthesize it by mixing and matching elements from its new
corpus.

This affected several different constructor types: splat, diagonal-
matrix, compound and array.

7bd3f1cc78 Fix fuzzer-discovered assertion with global variables.
Our analysis pass for checking if an expression is a constant-expression
would assert if the expression contained a TypeReference or a
FunctionReference. This could happen if you passed in an expression that
had not yet been type-coerced. This check seemed overly strict, so the
assertion has been removed (although such an expression will be reported
as 'not a constant expression').

This bit us in global-variable declaration, where we checked if a
global variable's initial-value expression was constant before coercing
it to the variable's type. This has also been reordered so the type-
coercion happens first. (Either order is now valid, but the type-
coercion related errors tend to be more detailed.)

8d13084535 Migrate function-body finalization out of IRGenerator.
This is a first step towards replacing `finalizeFunction` with a
`FunctionDefinition::Convert` method living outside of the IRGenerator.

Previously this code would assert that we had no early returns from a
vertex-program main() method; this has been turned into an error.
(The original assertion was also tied to fRTFlip, because the *problem*
with early-returns in main is tied to the lack of RTFlip fixups, but
we fundamentally don't allow early returns, so it makes more sense to
just universally disallow it.)

c26cf6c2f5 Guard against width/height overflow in SkIRect::subtract
SkRectPriv::Subtract had assumed that Sk[I]Rect::Intersects returns
false if either argument is empty. However, when an SkIRect with
overflowing dimensions is intersected with a non-overflowing SkIRect,
then the intersection can be valid and the remainder of the impl's
expectations are violated because dimensions are "negative".

Since these overflowing rects are considered empty anyways, this just
explicitly checks for that.

842ee5bd8d Fix assertion when calling a built-in function at global scope.
The fuzzer invented a much more elaborate example, but I was able to
winnow it down to a simple otherwise-normal test case. This also fixes
a latent DSL bug; DSL functions were not updating the list of referenced
intrinsics, so the compiler might emit finished programs that called
built-in functions that didn't exist in the code.

bb8cf5804c Fix invalid variable ref-kind discovered by fuzzer.
No-op arithmetic simplification will convert expressions like `x += 0`
to `x`. When making this simplification, we will also downgrade the ref-
kind of `x` from "write" to "read" since the new expression is no longer
an assignment.

The fuzzer discovered that the ref-kind downgrade was too aggressive,
and would also traverse into nested subexpressions and downgrade them
as well. That is, for `x[y=z] += 0` would convert both `x` and `y`
into "read" references, which is incorrect; `y` is still being written
to.

The fuzzer managed to turn this mistake into an assertion by leveraging
a separate optimization. It added a leading, side-effect-less comma
expression for us to detect as worthless and eliminate. In doing so, we
clone the expression with the busted ref-kind, triggering an assertion.

Our SPIR-V code generator did not implement support for negating a uint.
However, this is something that GLSL allows (as does the rest of SkSL).
I checked glslang and it uses OpSNegate here. The SPIR-V docs indicate
that OpSNegate allows any type of integer, and the validator lets it
pass, so we now use OpSNegate here as well.

An array would be applied to ALL variables in the decl after its initial
appearance. That is, `int w, x[10], y, z;` would be interpreted as
`int w, x[10], y[10], z[10];`. The fuzzer caught this by putting two
arrayed variables in a row; the second variable was interpreted as a
nested array, which led to an assertion.

This CL contains a simple hand-written test case demonstrating the bug,
with the fix coming in a followup.

f95048cc4d Report intermediate expressions as errors in For next-exprs.
We weren't coercing the expression because we don't care about its type,
but that allowed intermediate-expressions to pass through without
reporting an error. Now we coerce the expression to its present type,
which will always fail if the type is disallowed and succeed otherwise.

f8a550491e SkSL: Use type-specific sampling intrinsics, rather than fn-call syntax
After further discussion, using intrinsics with signatures similar to
sample keeps us looking like GLSL. However, using "sample" is still
misleading, so this adds explicit "shade", "filter", and "blend"
intrinsics. After migrating clients, the "sample" versions will be
removed.

3f37322d71 Fix const function-parameter assertion discovered by fuzzer.
During constant-folding, we baked in an assertion stating that any
const-typed variable reference ought to have an initial value, because
you can't declare a const variable without assigning a value. However,
function parameters are an exception to this rule! They are variable
references and are allowed to be const, but will not have an initial
value. (In this case, `const` just means you can't alter the value.)

In this case, all we needed to do was remove the assertion; we already
treated this case defensively and with the appropriate care.

d361690358 Fix diagonal-matrix assertion discovered by fuzzer.
This was another place where we needed to use
`getConstantSubexpression` to rebuild vectors/matrices; it is a more
robust approach than trying handle each ctor type individually. The
fuzzer found an edge case with double-casting matrices to vectors that
fell through the cracks with the original approach.

In adding additional tests, I also found a case that the constant-folder
seems to ignore, `bool4(x,x,x,x) == bool4(x)`. This does fold for ints
and floats, so this ought to be fixable in a followup, but it's not a
big deal either way; this is very unlikely to occer in real code.

RoundEven isn't available in lower shader models of Direct3D;
SPIRV-Cross throws if it's unavailable. We may need a caps bit for this.

Also, a variety of tests around similar error conditions were added.

9078a89b26 Avoid mix-up between MAIN_COORDS and FRAGCOORD.
When compiling test shaders, we were setting SK_FRAGCOORD_BUILTIN on the
`coords` parameter to main() instead of SK_MAIN_COORDS_BUILTIN. These
two built-ins don't have the same type (float2 vs. float4) and don't
mean quite the same thing.

The SPIR-V code generator saw a variable with the SK_FRAGCOORD_BUILTIN
builtin value and assumed the presence of a global variable named
`sk_FragCoord`, which didn't exist (because it was never referenced in
the code, so it was never cloned in from the sksl_frag module).

This is only a concern when compiling test shaders with skslc; real
shaders don't hit these code paths. The generated code here is still
imperfect; if you look closely, you'll see the GLSL and Metal code is
referencing the `coords` variable but it's never declared anywhere.

b0697081b5 Improve SPIR-V handling of RTFlip when running the fuzzer.
If the passed-in shader references RTFlip (i.e., sk_FragCoord is used),
the settings must contain RTFlip layout info; otherwise, an error
occurs. Originally, the fuzzer detected this as a problem because the
error was being delivered via SK_ABORT, but it's failing more cleanly
now that Ethan's new error handling code is in place (causing the fuzzer
to report that the bug was "fixed"). With this CL, the oss-fuzz shader
will actually compile successfully in SPIR-V instead of leading to an
error.

823c504999 Include non-ES2 numeric types in the root symbol table.
Previously, we hid non-ES2 numeric types from Runtime Effect code by
only including them in the private symbol table. Now, they are present
in the root symbol table, but marked with a new flag that identifies
them as disallowed in ES2.

The IR generator now enforces that strict-ES2 code doesn't contain types
that aren't allowed. This has two benefits:
- Intrinsic functions in sksl_public can now reference these types
- Error reporting is nicer

eb0f29dba2 SkSL: Allow invoking children (shaders, etc) like functions
Previously, you would declare child objects (shaders, colorFilters, etc.)
and "sample" them like this:

    uniform shader input;
    uniform colorFilter filter;
    half4 main(float2 coord) {
        half4 inColor = sample(input, coord);
        return sample(filter, inColor);
    }

With the new syntax, those child objects become directly callable,
reflecting the way that Skia assembles all parts of the paint (as functions)
in the overall fragment shader:

    uniform shader input;
    uniform colorFilter filter;
    half4 main(float2 coord) {
        half4 inColor = input(coord);
        return filter(inColor);
    }

c18ee4e55a Honor component type in Metal matrix helper functions.
Right now, Metal forces types to full precision. The matrix helper
functions previously baked in that assumption by hard-coding "floatX".
Now, they honor the component type; if this->typeName() started
returning "half", our helper functions would be named with "halfX". This
would allow half-precision and full-precision helpers to coexist.

properly in the face of custom error handlers. There is probably more
work to be done in that area, but this at least passes all existing

Note that the CPU backend still doesn't have support for these calls,
and will fail ungracefully (assertion, nonsense result) if these
intrinsics are used.

The testing here is limited, due to an unrelated bug in SPIR-V

This function was already divided into several different tests, but each

it apart into smaller functions which should be easier to reason about.

This CL also fixes a handful of variable shadowing issues in the code.

26487162fe Add support for array-cast syntax in SkSL.
Compiling a program with "allow narrowing conversions" actually fixes up
narrowing casts in the program by inserting casts wherever they would be
needed for type-correctness. For instance, compiling the statement
    `half h = myFloat;`
inserts an appropriate narrowing cast:
    `half h = half(myFloat);`.

The Pipeline stage code generator relies on this behavior, as when it
re-emits a runtime effect into a complete SkSL program, the narrowing-
conversions flag will no longer be set, but that is okay, because the
emitted code now contains typecasts anywhere they would be necessary.

Logically, this implies that anything which supports narrowing
conversions must be castable between high and low precision. In GLSL and
SPIR-V, such a cast is trivial, because the types are the same and the
precision qualifiers are treated as individual hints on each variable.
In Metal, we dodge the issue by only emitting full-precision types. But
we also need to emit raw SkSL from an SkSL program (that is what the
Pipeline stage generator does).

SkSL already supported every typical cast, but GLSL lacked any syntax
for casting an array to a different type. This meant SkSL had no array
casting syntax as well. SkSL now has array-cast syntax, but it is only
allowed for casting low/high-precision arrays to the same base type.
(You can't cast an int array to float, or a signed array to unsigned.)

3c991fd72c Fix duplicated array types in SPIR-V.
Previously, SPIR-V would generate two separate SpvIds for array types if
they differed in SkSL, even if they matched in SPIR-V. For instance,
`half[10]` and `float[10]` are the same SPIR-V type, so they should
reuse the same SpvId. (The RelaxedPrecision decoration doesn't go on the
type.)

This is important because OpLoad and OpStore require the same SpvId on a
variable; you can't OpLoad from one type SpvId and OpStore to a
different type SpvId, even if the underlying type behind the SpvId is
the same.

(A slightly simpler fix exists at http://review.skia.org/437237, but
this triggered a memory pooling bug that I can't properly debug from
this machine.)

23d8f94535 Fix array-of-matrix/struct comparisons in Metal.
Metal needs helper functions in order to compare arrays, structs, and
matrices. Depending on the input code, it was possible for the
array-comparison helper to be emitted before a matrix-comparison
or struct-comparison helper. If this occurred, array comparisons of that
matrix or struct type would fail, because the operator== for the array's
inner type was defined after array==, and Metal (like C++) parses
top-to-bottom and only considers functions declared above the current
function.

We now emit prototypes for all the array, struct and matrix helper
function. These prototypes are emitted above any helper functions. This
ensures visibility no matter how your comparisons are organized.

130338c9e1 Fix array-of-vector comparisons in Metal.
Comparing `vec1 == vec2` returns a bvec in Metal, so the result must be
wrapped in `all()` in order to boil it down to a single boolean result.
Our array-comparison helper function did not do this. Fortunately,
`all(scalar)` is a no-op, so we can just wrap the result unilaterally.

307f8f525a Simplify the boilerplate of cloning a fragment processor.
GrFragmentProcessor now provides an (explicit) copy constructor which
clones all child processors and flags from the passed-in FP. Since we no
longer have flags which propagate up to the root node of the FP tree,
all flags are now safe to copy, since a cloned FP also clones all of its
children.

We were previously using a mix of pass-by-value and pass-by-pointer (to
allow for explicitly null PositionInfo). Being able to pass a null
PositionInfo didn't really add much, since we can just use a nullary-
constructor PositionInfo instead, so these have all been migrated to
by-value.

When we finally make SkPath immutable, we won't need this field at all.

Note: this CL "fixes" the last 2 columns in path_append_extend gm.
They should appear the same as the previous 2 columns.

e3f85e07fa Add improved regression test for oss-fuzz:36655.
Most of the code generated by the fuzzer is nonsense, but there is a
method to its madness. The crash is only triggered under specific
conditions:
- The runtime effect has enough helper functions to mostly fill up the
  call graph hash-map. It won't rehash until it gets close to capacity.
- There must be several calls to built-in functions, in order to add
  elements to the call graph to force a rehash.

The fuzzer-generated code manages to satisfy both these requirements.

e3ae968f5f Enable comparison of arrays of different precision types.
GLSL allows an array of `lowp float` to be compared against `highp
float` seamlessly because the types are considered to be the same. SkSL,
however, treats these as different types, so we need to coerce the types
to allow this comparison to work.

In other words, these comparisons can cause an array to be implicitly
casted. The expression `myHalf2Array == float[2](a, b)` should be
allowed when narrowing conversions are enabled. To allow this to work,
we need a dedicated IR node representing this type coercion.

We now allow implicit coercion of array types when the array's component
types would be implicitly coercible, and have a new IR node representing
that implicit conversion.

This CL fixes array comparisons, but array assignment needs additional
fixes. It currently results in:
    "type mismatch: '=' cannot operate on (types)".

9ae6ea0711 Fix fuzzer-discovered error with swizzling matrices.
The optimization logic for swizzling a constructor assumed that every
argument to the constructor was a scalar or vector. When it was written,
this assumption was true. However, we recently added support for casting
mat2x2 to float4 which violates the assumption.

We now check every argument and do not attempt to optimize if a
non-scalar, non-vector arg is found.

3b39b7f5c6 Alias canComputeFastBounds to affectsTransparentBlack
This moves SkImageFilter's API closer to SkColorFilter's, and also
updates SkRecordDraw's PaintMayAffectTransparentBlack to be less
conservative.

Originally:
-canComputeFastBounds() handled aggregating behavior of the entire graph
  but it's a public API
-affectsTransparentBlack() was the private virtual for a specific node

Now:
-affectsTransparentBlack() handles aggregating behavior of the graph and
  is part of SkImageFilter_Base (mirroring SkColorFilter_Base).
-added onAffectsTransparentBlack() to clarify the per-node virtual that
  they can override.
-canComputeFastBounds() simply returns !affectsTransparentBlack().

There are some usages in our code that I kept using canComputeFastBounds
(e.g. SkPaint's computefastBounds) because it kept naming consistent.
In other places I updated to use affectsTransparentBlack since I thought
that made it clearer why we were checking that behavior.

68587ae274 Add SkClipStack::replaceClip() separate from deprecated clip op
The replaceClip functionality was added to allow Android to move off of
generalized expanding clips. At the time, SkClipStack simply used the
kReplace_SkClipOp to handle it. In order to remove those expanding ops,
SkClipStack will need a proper implementation of replaceClip().

The clip elements have an additional field to mark if
it's a replace (and it's op will be kIntersect). Adds a temporary
getRegionOp() function to unify elements that use this field vs.
elements that use the deprecated clip op (i.e. if they were deserialized
from an SKP that recorded an expanding op).

Clients of SkClipOp that checked for replace ops use the new function
instead of referring to the enum value directly.

SPIR-V code generation synthesizes some extra variables that don't
actually exist in the Program. Checking the ProgramUsage of these
variables would fail; ProgramUsage::get doesn't know about these
variables, so it asserts (and would consider them as dead even if it
didn't assert). We now track our SPIR-V bonus variables in a separate
set, and always report them as live.

replaces "class GrSurfaceDrawContext;" with

replaces "GrSurfaceDrawContext*" with "auto" where possible
replaces "rtc" with "sdc"
replaces "surfaceDrawContext" with "sdc"
replaces GrSurfaceDrawContext with skgpu::v1::SurfaceDrawContext
reflows parameters as needed

This CL does not try to:

make skgpu::v1::SurfaceDrawContext V1-only
minimize the skgpu and/or skgpu::v1 prefixes

Those two tasks will be accomplished in follow up CLs. This CL is just trying to get the bulk of the mechanical changes comprehensibly landed.

a4953515af add array to the Uniforms
Note: I have changed from using a byte offset for index to
an ordinary array index at the builder interface, but the
builder converts this to a byte offset for the instruction.
This makes the API easier to use.

I've added pushArray, and pushArrayF to the Uniforms, and
convenience methods on the builder to take Uniforms.

I've expanded the tests to use the new API.
