adb3eac15c Add tests for array assignment with narrowing conversions.
An assignment like `mediump int a[2] = myHighpIntArray;` should succeed
now that the previous CLs have landed; originally, this would have
caused a type-mismatch error.

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.)

2fa273eecf Reland: [COLRv1] Support retrieving ClipBox.
Reland after MSAN failure, initializing SkRect to empty in
computeColrV1GlyphBoundingBox().

After the discussion in [1] which was filed also in response to feedback
from Ben, the COLRv1 spec moved to not using a bounding box derived from
the `glyf` glyph for a give glyph id, but instead either use a ClipBox
found for a particular glyph id range from a ClipList array in the
COLRv1 table. If such a ClipBox is not found, perform a traversal of the
COLRv1 graph to compute the union of rectangles to compute a bounding
box.

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.

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.

The fuzzer quickly discovered that the newly introduced mat2-to-vec4
conversion code did not account for integer vectors. We now handle
`ivec4(mat2)` casts properly. This required some non-trivial
restructuring of the logic, but in the vast majority of cases, the types
will match and the end result will be identical.

d8d85b9b89 Reland "Don't key progams/pipelines on origin.""
Reland works around Adreno issue with this formulation of sk_Clockwise:
 (sk_RTFlip.y < 0.0 ? !gl_FrontFacing : gl_FrontFacing)

and instead adds this to the top of the function:
 bool sk_Clockwise = gl_FrontFacing;
 if (sk_RTFlip.y < 0.0) {
      sk_Clockwise = !sk_Clockwise;
 }

Original description:

SkSL language features that are origin sensitive now use a uniform
to conditionally flip their result rather than generating different
code.

Previously we would insert a "rt height" uniform if sk_FragCoord needed
to be flipped. sk_FragCoord,y was implemented as "realFragCoord.y" or
"rtHeight - realFragCoord.y" depending on SkSL::ProgramSettings::fFlipY.

Now we instead use a two component vector rtFlip and sk_FragCoord.y is
always "rtFlip.x + rtFlip.y*realFragCoord.y". We configure rtFlip as
either (0, 1) or (rtHeight, -1). sk_Clockwise and dFdy simiarly use
rtFlip.y to emit code that always works with either origin.

50d0d097c3 Add dest-color support to the Pipeline stage.
Previously, when converting a program, the pipeline stage could assume
that an input to main() of type half4/float4 was always the input color.
This was a good assumption since the only possible inputs were
coordinates, or the input color.

This CL now recognizes that when a second float4 is passed to the main()
function, it should be a SK_DEST_COLOR_BUILTIN. This will let blend
functions pass in two colors.

ProgramToSkVM now takes a dest-color argument as well, but existing call
sites won't reference it (since they aren't for blend functions). I've
just passed the input-color a second time, since the value will never
actually be accessed.

these are only accessible via skslc; there's no Runtime Effect API to
create one and the dest color isn't hooked up to anything.

$genType mix($genType x, $genType y, $genBType a);
$genHType mix($genHType x, $genHType y, $genBType a);
$genIType mix($genIType x, $genIType y, $genBType a);
$genBType mix($genBType x, $genBType y, $genBType a);

The top half were simple to implement via `evaluate_3_way_intrinsic`.

The bottom half--`x, y, $genBType`--required adding basic support into
`evaluate_n_way_intrinsic_of_type` for mixed argument types, since `x`
and `y` could be of any numeric type, but `a` is always boolean.
Fortunately, this didn't require major changes.

598c5e5b07 Implement compile-time optimization for matrixCompMult().
$mat matrixCompMult($mat x, $mat y);
$hmat matrixCompMult($hmat x, $hmat y);

This required some minor changes to `evaluate_n_way_intrinsic_of_type`
to allow the inputs to be matrices instead of vectors. Fortunately, most
of the moving parts were already generic/flexible enough that this just
worked, but some explicit checks for `x.isVector` needed to become
`!x.isScalar()`, and `columns` needed to become `slotCount`.

b0d93ccc90 Detect out-of-range integer assignment.
Now that we know the minimum and maximum values of a given integer Type,
we can check for assigment statements or variable initial-values that
exceed those bounds and report it as an error. This check should work on
anything that can be optimized or folded down to an IntLiteral, but
isn't meant to be 100% exhaustive.

3c74a5357a Add GLSL workaround for 4x2 diagonal matrix bug.
GLSL now emits 4x2 diagonal matrices as:
	`(mat4x2(1.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0) * n)`
instead of
	`mat4x2(n)`.

This works around a long-standing GLSL bug in both Mesa and glslang that
affects several drivers:

f2b08cc9c8 Fix SPIR-V code generation of dead return statements.
If we encounter code like `return 1; return 2;` we need to synthesize a
label, even though the second return statement isn't actually reachable.
This is harmless and satisfies the SPIR-V validator.

Ideally we'd eliminate the dead code entirely, but this case is rare and
isn't likely to cause any problems as-is.

bdf3bb7b5f Add support for componentwise matrix divide in SPIR-V.
All the pieces of the puzzle were already here to support componentwise
addition and subtraction of matrices. Division was just a forgotten gap
in the implementation and is now patched up to match + and -.

NOTE: if you read the SPIR-V output very closely, you may be surprised
that there are fewer FDiv operations than you'd expect from reading the
input SkSL. As it turns out, a preexisting optimization is rewriting
`mat / 4` into `mat * 0.25` (see line 2689), and this rewritten form can
use the dedicated MatrixTimesScalar op. So we only get componentwise
FDivs for the `4 / mat` lines in the source.

ab3e6394a0 Re-enable the nonsquare matrix test.
The mat4x2 portion of the test no longer checks its results, as there
are bugs in the Intel and Radeon GPU drivers that prevent mat4x2s
from being constructed properly.

The SkSL optimizer ends up eliminating the 4x2 matrix entirely because
it is unused by the rest of the code, as well at the 4x4 matrix which is
calculated from the 4x2. At this point, I'm OK with this.

1dc2d0fe0f Allow compile-time intrinsic evaluation to read const variables.
Previously, the code neglected to resolve constant variables into
values. This meant that expressions like `lessThan(zero, one)` could not
be compile-time evaluated even when `zero` and `one` have known values.

If every argument passed to any() or all() is a compile-time constant,
we now detect this and optimize away the function call entirely.

Future CLs will perform a similar optimization on other intrinsic calls
which can be detected and eliminated at compile time, like lessThan().

8c9ccc8ad1 Optimize compound constructors containing constant vars.
A constructor like `float2(one, two)` is not a compile-time constant, so
we miss optimization opportunities like folding. Constant variables
inside compound constructors are now replaced when optimization is on,
so this would optimize down to `float2(1.0, 2.0)` and be eligible for
folding.

This is a reland of 830c69ca66

Original change's description:
> Implement operator== and != for Metal structs and arrays.
>
> GLSL/SkSL assumes that == and != on struct/array types should work.
> We need to emit equality and inequality operators whenever we find code
> that compares a struct or array.
>
> Structs and arrays can be arbitrarily nested, and either type can
> contain a matrix. All of these things need custom equality operators in
> Metal. Therefore, we need to recursively generate comparison operators
> when any of these types are encountered.
>
> For arrays we get lucky, and we can cover all possible array types and
> sizes with a single templated operator== method. Structs and matrices
> have no such luck, and are generated separately on a per-type basis.
>
> For each of these types, operator== is implemented as an equality check
> on each field, and operator!= is implemented in terms of operator==.
> Equality and inequality are always emitted together. (Previously, matrix
> equality and inequality were emitted and implemented independently, but
> this is no longer the case.)

65d7ab2c07 Loosen ES3 restrictions in Runtime Effects for debugging.
This CL adds a RuntimeEffect option flag which skips over the various
`strictES2Mode` checks sprinkled throughout IR generation.

Runtime Effects still won't allow a lot of ES3 things (the Pipeline
stage will reject unsupported statement types, SkVM doesn't support most
non-ES2 constructs, etc). However, this change will give us the ability
to test many more features involving arrays and structs that previously
were off-limits due to ES2 restrictions, and will shore up some
legitimate gaps in our testing. This is a useful starting point to allow
for improved test coverage.

a global with the expression
    abs(rect.x) > 16000 || abs(rect.y) > 16000 ||
    abs(rect.z) > 16000 || abs(rect.w) > 16000

b9fc6e45c2 Support 'layout(when)' expressions in DSL C++.
This required some changes to how we name variables in DSL.
When-expressions are designed to expect a local C++ variable with the
same name as the layout key. This constraint means our DSLVar variables
CANNOT have the same name as the layout key. Now, all DSL variables are
given a prefix. We try to keep the code tidy by using just a leading
underscore as the prefix, where it's safe to do so. (The C++ naming
rules put some underscore-names out of bounds, but underscore followed
by a lowercase letter is safe.)

c412688798 Reland "Implement statements and expressions in DSL C++ code generator."
This is a reland of 16cbfb41df

Tests now rely on `shaderDerivativeSupport` and `integerSupport` as
proxies to indicate ES3 support. The SwitchStatement test has been
adjusted to hopefully confuse fewer compilers.

49b409e680 Simplify for init-stmts at the IR level.
Most backends don't like init-stmts with multiple VarDeclarations inside
them, so we no longer emit IR that does this. This lets us avoid doing
backend-level fixups.

This was an experimental feature. It worked (but only the GPU backend).
It was never adopted or used by anyone, to my knowledge. It's a large
amount of code, and a strange corner of SkSL for users to stumble into.

cbb60bd0b0 Add runtime color filter and shader modes to the SkSL compiler
These enforce stricter rules about the signature of main, and each one
uses a separate pre-include module. That prevents color filters from
being able to reference sk_FragCoord (or coords passed to main) at all.
It also limits the versions of sample() that are exposed.

In the new world, an effect created for a specific stage of the Skia
pipeline can only be used to create instances of that stage (SkShader or
SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect,
which continues to be more lenient and allow creation of either shaders
or color filters from a single effect. After we migrate all clients, we
can deprecate and then delete that mode.

82ab3409f7 Fork CPPCodeGenerator into a DSL-based version.
The long term goal is for the DSLCPPCodeGenerator to replace the
CPPCodeGenerator entirely, but we will need both to coexist while DSL is
still under development.

Currently, the DSLCPPCodeGenerator is cloned from CPPCodeGenerator and
emits almost exactly the same code (it adds a comment at the top to
distinguish its output). Its output will change in followup CLs.

This CL also allows skslc to recognize the `_dsl.cpp` output suffix and
generate code using DSLCPPCodeGenerator instead of CPPCodeGenerator.
This allows test DSL FPs to be created for inspection.

d02615698e Fix assertion when performing type-coercion with enums.
In http://review.skia.org/393397, I replaced a Constructor::Convert call
with a call directly to ConstructorCompoundCast::Make.

This worked fine if the input expression was actually a compound, but
if it was not, the code would assert/crash. The fuzzer detected this
error right away. (Enums are not considered to be a scalar, a vector or
a matrix in SkSL.)
