a655a33264 Rename glrt::fRTFBOID -> fMultisampleFBOID
As part of this we also create two fbos now for
multisampled_render_to_texture: one msaa and one not.

We believe with advent of  GrBackendSurfaceMutableState that this is
only needed for inline atlas uploads. Those call GrGpu directly.

5abb9e1426 Represent matrix resizes as a dedicated expression type.
This shook out a long-standing bug; constant folding would treat a
matrix resize as if the cells not covered by the original matrix were
all zero. This is wrong; GLSL populates the unknown cells with an
identity matrix. We actually tested for the wrong behavior, so the tests
were updated to match the correct behavior, and an equivalent test was
added that does not constant-fold (to verify that our constant folder
matches reality).

5a2de5e72f put an arena on GrSurfaceDrawContext
This is part one of two CLs. In this CL, I put a
sk_sp<GrArenas> on GrSurfaceFillContext where GrArenas wraps
a SkArenaAlloc to add ref counting. Creating
a GrOpsTask shares the GrArenas with the ops task. New plumbing
was added to GR_DRAW_OP_TEST_DEFINE to allow a proper
GrSurfaceDrawContext to be passed to GrAtlasTextOp's
GR_DRAW_OP_TEST_DEFINE so the arena will have a proper lifetime.

The second CL will work on replacing GrOpsTask's fAllocators
system with the shared arena.

9267183cf4 Fix matrix resizing in SPIR-V.
When growing a matrix, the new cells should contain the identity matrix.
`writeMatrixCopy` was populating every cell with zeros instead.
Also, `writeMatrixCopy` had some code for handling int matrices, but
we don't support this in SkSL anywhere else; replaced with an assert
that the component type is float.

b14a819122 Represent vector-cast constructors with ConstructorVectorCast.
Making a VectorCast from a compile-time constant will perform the cast
at compile-time instead; previously, we did not apply this optimization.
This simplified a few test outputs in subtle ways. (In particular, the
SPIR-V codegen used to occasionally decorate OpConstantComposite of
constant numbers with RelaxedPrecision, and no longer appears to do
this. This should have no effect on results either way AFAICS.)

Because we don't return VectorCast constructors containing compile-time
constant values, we do not need to implement compareConstant for this
constructor; they only wrap non-compile-time-constant expressions.

We don't directly support this today at all. In practice, though, simple
constant arrays are detected as equal in the constant-folding pass
because they hit the `x == x` self-equality check (using
`IsSameExpressionTree`).

This does not work for our inequality tests, though, so those do not
fold.

1d2a26d0df Add more comprehensive test for GPU write pixels.
Similar to existing SurfaceContextReadPixels but for writes. Tries all
combinations of src/dst color type and alpha type for write pixels.
Always reads back pixels for verification using the ImageInfo of the
tested surface context.

fabed8bb79 Fix fuzzer-discovered error with variable declarations.
As soon as a single VarDeclaration is successfully created, its Variable
is added to the current symbol table. However, if a variable-declaration
line declared several variables in a row, we would stop if ANY of the
declarations contained an error and discard the entire statement, but
would continue processing the rest of the program. This left us in a
position where some Variables existed in the SymbolTable with valid,
reachable names, but their corresponding VarDeclaration statement had
been thrown away as erroneous. Since Variables point back to
VarDeclarations for their initialValues, this gave us a stale pointer.
Any future reference to that variable name which could trigger an
access to its initialValue would read from this dead pointer.

This CL fixes the conversion of VarDeclarations so that we no longer
throw away any VarDeclarations associated with a successfully-parsed
Variable.

2396fb8be5 Convert division-by-literal in SPIR-V to multiplication.
This is particularly relevant for "vector / scalar" divides, as these
end up generating an extra OpFDiv to take the reciprocal of the scalar.
This meant we were generating code to calculate "literal 1 / literal N"
at runtime whenever dividing vector V against scalar N. This fix moves
the reciprocal calculation to compile-time. And of course, it's a valid
strength reduction in all cases.

d94bfdd7d8 Fix codegen for integer vector-scalar arithmetic in SPIR-V.
Due to missing type-checks, we would emit `OpVectorTimesScalar` when
multiplying an ivec with an int, or an `OpFDiv` when dividing an ivec
against an int.

2febb5b423 Add SkSL test for vector-scalar math.
We had constant-folding tests for vector-scalar arithmetic, but didn't
have an equivalent SkSL unit test for vector-scalar arithmetic that
actually needs to be computed at runtime.

This exposes two SPIR-V bugs: one was previously known, but the other
is a new discovery.

Previously, these tests were never actually executed, only read during
code review. They are now properly tested for correctness whenever dm
is run. Non-ES2 compliant statements (do/while/switch) are unfortunately
excluded here, as they are not compatible with Runtime Effects yet.

9e13fe86b1 Rewrite matrix * vector multiplication on ARM GPUs.
If sk_Caps.rewriteMatrixVectorMultiply is false, we generate the same
code as before.

If sk_Caps.rewriteMatrixVectorMultiply is true, and optimization is
enabled, medium-precision multiplication of `matrix * vector` is
rewritten in BinaryExpression as the sum of
(m[0]*v[0] + m[1]*v[1] + ... + m[N]*v[N]).

85749c0b22 Add caps bit for RewriteMatrixVectorMultiply.
On ARM GPUs, the Vulkan driver does not honor relaxed precision when
evaluating SpvOpMatrixTimesVector. This leads to reduced performance
(compared to GLSL, where mediump matrices and floats do evaluate all
intermediate values at mediump).

This caps bit will be enabled on ARM GPUs and, in a followup CL, will
be used to toggle a workaround where `m*v` is rewritten as the sum of
(m[0]*v[0] + m[1]*v[1] + ... + m[N]*v[N]).

functions to get inlined, even if inlining was disabled during the
initial SkSL generation. This meant that the "NoInline" path was not
actually very effective.

- UseWithoutInitialize...: we no longer track variable use-before-init.
- InlineDivideByZero: we no longer constant-fold the result of an
  inlined function call into its parent statement.
- Unreachable: we no longer report unreachable statements.

And fixed some minor test-case issues:
- StaticSwitchConditionalBreak: we still check this, but the function
  was being dead-stripped before this check could run. Renamed to main.
- OssFuzzXxxxx: these cases no longer report errors, but they are still
  valuable as regression tests; moved to `shared/`.
