1991780081 Update LoopFloat/LoopInt tests to reduce hoisting.
Previously, none of our `runtime` tests relied on the input coordinate
in any way, so all of the logic was hoisted above the main loop in every
test. This CL adds an artificial reliance on the input coordinate so
that we have at least some SkVM tests with real code in the main loop.
This lets us see debug trace instructions interleaved with real code.

The input coordinate is clamped against a known uniform value
(`colorGreen` always contains 0101) so that the final test output
remains consistent in practice.

Additionally, I noticed that this test was only enabled in ES3, but
it doesn't seem to have anything ES3-specific in it, so it's now
enabled across the board.

05c41162fb Allow inlining of functions with unassigned out-params.
Our inliner would ignore any functions with `inout` parameters, because
inlining them properly was more complex than just leaving the function
call. However, real-world code can sometimes contain helper functions
that have `inout` params that are never used at all (e.g. an uber-shader
with some features turned off).

We now read the ProgramUsage and check to see whether or not the
`inout`-qualified parameter is actually modified. If it's never changed,
the function now remains a candidate for inlining.

6ee5d9e3c9 Improve index-folding of arrays and matrices.
Yesterday's implementation was close but I realized later that it wasn't
quite ideal.
- Array index-folding was gated on `isCompileTimeConstant`, which is too
  strict. The real limitation is `hasSideEffects`. If an array contains
  a side-effecting expression, we should leave it alone. Otherwise it
  is safe to pluck out an element from the array and toss the rest.
- Matrix index-folding was gated on `getConstantSubexpression` for the
  extracted elements, but did not check the other elements at all. This
  was too lenient; we now only proceed to the folding step if
  `hasSideEffects` returns false.

I added some tests to verify the final behavior and also discovered a
small related issue. Diagonal matrices were not substituting literals
in for constant-values, which inhibited folding as well and would break
constant-expression evaluation. This is now fixed.

d92f9c2f8d Add tests for matrix constant-expressions.
We should support constant-expressions involving matrices (GLSL ES2
does, WebGL does). We currently don't. We do properly report out-of-
range indexing, but we don't optimize away valid matrix index
expressions or allow matrices to be indexed in a constant-expression
context.

76c1ff1566 Optimize indexing into an array with a constant-expression.
Previously, SkSL was unable to resolve the constant expression `x[y]`
for a constant-array `x` and a constant-integer-scalar `y`. Now, if `x`
and `y` are known, we can replace `x[y]` with the indexed array element.

Note that we need to be careful here, as it's not a valid optimization
to eliminate array elements that have side effects. We preserve side-
effecting expressions using the comma operator.

0b84159e3b Improve array-indexing tests.
Previously, we didn't have tests which leveraged constant-evaluation of
array indexing (because we didn't support it), and our test files
commingled constant-indexing into vectors with constant-indexing into
arrays.

The test files now separate vector- and array-handling into separate
tests, and a ton of new cases have been added to ArrayFolding. The
ArrayFolding tests now require constant-evaluation of array indexing,
so they fail in this CL, but will be fixed in the followup CL.

6e6ae1b762 Fix inlined out-of-range vector access.
Previously, this code assumed that IndexExpression::Convert had done
range checking and that it was safe to access the base expression at
the passed-in index. The inliner violates this assumption, because it
can replace unknowns (where out-of-range access is undefined but non-
fatal) with knowns (where out-of-range access is forbidden).

We now do range-checking inside IndexExpression::Make and report the
error cleanly, instead of asserting inside of Swizzle::Make due to an
invalid component index.

ee525493ea Add test for incomplete expressions.
The ExpressionStatement currently eliminates dangling references without
reporting them as an error. This happens due to optimization; these
expressions (being meaningless) have no side effects, and so the
optimizer replaces them with Nop. When the optimizer is off, these
programs trigger an assert:

3b6e07098b Enable constant-expression folding at all times.
In some contexts, we rely on constant expressions to fold in order for
SkSL to work properly. (e.g. an array size is allowed to be any
constant-expression in GLSL, but the compiler really needs to know the
actual size). Previously, turning off optimization would break several
tests. Now, constant-expression folding always occurs even when the
optimizer is disabled.

Note that disabling the optimizer isn't an end-user option, so this
only affects internal usage.

1f8c31b101 [infra] Add initial Bazel rules and files
These rules can be used to build our GMs on WASM+WebGL and
libskia.a with just the CPU backend (and most other features
turned off).

This can be done with the following commands:
  - bazel build //modules/canvaskit:gm-bindings-wasm --gpu_backend=gl_backend --with_gl_standard=webgl_standard
  - bazel build :skia-core --config clang

This pivots slightly from http://review.skia.org/463517
by using config_settings [1] instead of platforms for
the optional features that we control. This pivot was
suggested in [2]

We have BUILD.bazel files in many of the subdirectories
that specify filegroups for the appropriate files. In
an effort to make //BUILD.bazel more readable, it is
the responsibility of these subfolders to deal with
conditionally including certain .h or .cpp files.
This is done using select statements and config_settings
or platform constraints as necessary.

For example, src/gpu/BUILD.bazel will different private
filegroups for each of the supported gpu backends [3]
and a more-visible filegroup called "srcs" that has
the right selection of the private files to be used
for compilation.

An effort has been made to avoid using glob() in our
BUILD.bazel files. These file lists were made by using
`ls -1` and some regex to add in quotes. We might want
to make a helper script to assist with that, if necessary.

To specify which options we have, the settings in
//bazel/common_config_settings/BUILD.bazel have been
redesigned. They make use of a macro `string_flag_with_values`
that removes the boilerplate. Patchset 36 shows what the
file looks like w/o the macro.

The top level BUILD.bazel file will still need to use
some logic to handle defines, because local_defines is
a list of strings, not a list of labels [4].

Suggested Review Order:
  - WORKSPACE.bazel to see the new dependencies on the
    emsdk toolchain and bazel_skylib
  - bazel/common_config_settings/* to see the few settings
    defined (we have more to define, see BUILD.gn and
    //gn/skia.gni for ideas)
  - BUILD.bazel to see the "skia-core" cc_library rule.
    See also "gms" and "tests"
  - modules/canvaskit/BUILD.bazel to see the use of
    the emscripten "wasm_cc_binary" rule, which depends
    on the "skia-core", "gms", and "tests" rule. Note that
    it only builds some of the gms as a proof of concept.
  - The other BUILD.bazel files. Some of these are not
    platform or feature dependent (e.g. pathops). Others
    are (e.g. gpu).
  - All other files.

7cde28909f Enforce basic limits on function stack size in SkSL.
Functions that declare variables totaling more than 100,000 slots will
now generate an error.

This is only a partial mitigation to the problem, as a sophisticated
attack could still chain/nest multiple functions together to consume
extremely large amounts of stack. However, this mitigation is still more
sophisticated than our peers; both WebGL and glslang are susceptible to
similar problems, and in the general case (ES3+ with full flow control)
it's intractable.

8be6332748 Serialize foreground color caching requirement specialisation
Add a getter to SkTypeface to provide information on whether it
needs access to the foreground color (in COLR fonts) so that the
strike cache can determine caching requirements.

Since remote SkTypefaces do not have access to table information,
implement this as a serializable flag, with font-blob backed
implementations being able to return this based on whether they
have a COLR table or not, starting with FreeType.

Preparation for supporting foreground color in FreeType COLR

390edeb88d Fix fuzzer-discovered error with no-op arithmetic.
The fuzzer triggered this error in a strange way that involves parsing a
TK_INVALID token. The fuzzer's original input used \xFF bytes in the
shader text to do this. I replaced these with the ` character since it
behaved the same, but allows our test inputs to remain basic ASCII.

The root problem is that `cast_expression`, part of no-op arithmetic
simplification, can now fail because expressions like `int(4000000000)`
no longer get past Constructor::Convert. Previously we had assumed
`cast_expression` could never return null; now we check its result for
null before using it.

aa369d2b8e Fix error with inlined literals overflowing their types.
It's possible to write code containing errors that are only apparent
once the inliner runs. For instance, a function which takes a short and
returns its negative it is valid for most inputs, but undefined for
-32768 (because +32768 does not fit in a short). A function which takes
floats and casts them to ints is valid for many inputs, but not valid if
you pass in 5 billion.

This CL restructures our out-of-range integer error detection to report
errors cleanly in these cases instead of asserting. It also refactors
the range checking code to be usable in situations where we don't yet
have a Literal expression.

This avoids our public includes using a src header file
and messing with SkUtils.h, which apparently was used
by Android. That should be cleaned up in a separate effort.

because nothing seemed particularly GPU/Ganesh specific to them.

I moved the latter to SkTypes.h because we have other align
code there and former to src/SkUtils.h because I didn't know
where else it should go.

The primary motivation was removing the GrTypesPriv.h
include from src/core/SkBlockAllocator.h. I had attempted
some amount of #if SK_SUPPORT_GPU, but that's not as clean
here because both our CPU and GPU backends use the
SkBlockAllocator (as far as I could tell).

This also moves sk_memset* from SkUtils.h to SkOpts.h, because
SkOpts.h requires bringing in RasterPipeline, which seemed
like overkill.

4363cdb5ea Fix for fuzzer-discovered error with bitwise-not.
A recent CL (http://review.skia.org/464121) made it an error to coerce a
literal value to a type that cannot hold the value. The fuzzer found a
case where we assumed type-coercion of a literal would always succeed,
and failed to null-check the result. We now null-check the result.

f2d016f12e Fix for fuzzer-discovered error with negation.
Yesterday's negation-related changes (http://review.skia.org/464123)
exposed a flaw that the fuzzer was able to exploit. We were previously
able to assume that `simplify_negation` would always return a non-null
expression; in some cases, that is no longer true.

With this change, we no longer have any SkSL tests which are able to
make a Literal integer that overflows its type. Literal::MakeInt now
asserts that its value is within bounds. I look forward to the fuzzer's

e82c1c11bc Add support for vk drm format modifiers.
On linux we need to support drm format modifiers on vulkan images. When
we have a modifier it can restrict the allowed usages/features of the
VkImage.

The current use case we have for images coming into skia that have
these modifiers are from video decoders. All these images are only used
as sampled images in draws and they have no filtering applied.
Therefore, for now, instead of tracking all format and modifier pairs
to know what is supported, we internally set these images to be external
which already restricts their use to basic in shader sampling.

Additionally in chrome, all these images are coming in ycbcr conversions
already which we treat as external.

These are not very interesting right now, because the in and out types
boil down to the same thing (int/int, float/float). When half-
precision types are enabled, these helpers will be more useful. They
will return an array which casts each element from int-to-short or
float-to-half (or vice versa).

3793335614 [graphite] Update Shape to use skgpu::Rect and float2
Switches Shape to store kRect types as skgpu::Rect instead of SkRect,
although it can be constructed or set from an SkRect. It returns a Rect
from rect() and bounds() now.

Also switches out the line to be constructed from float2's, and re-use
the fRect storage to store the first segment vertex in topLeft and
the second vertex in botRight.

2fceb21cb7 [graphite] Add an IntersectionTree class
Implements a BSP tree with NEON/SSE optimizations that tracks
non-overlapping regions. This object can be used batch sets of paths
into non-overlapping draws. Performance on AppleM1 with our existing
benchmarks looks very promising:

    desk_motionmarkarcs.skp     1227 paths -> 69 draws    450us
    desk_motionmarksuits.skp    1417 paths -> 26 draws    201us
    desk_chalkboard.skp         1940 paths -> 11 draws     84us
    desk_ynevsvg.skp             859 paths -> 10 draws     31us
    desk_micrographygirl.skp     318 paths -> 29 draws     11us

ab0a13d9d9 Removed the final remnants of IRGenerator
This completes the long process of moving all of IRGenerator's code and
data into better homes and finally kills the class altogether. There is
a lot of #include churn here due to poor header hygiene in the past;
IRGenerator.h included a ton of stuff and almost everything included
IRGenerator, allowing us to inadvertently be sloppy with our includes.
