b617bced6e Use OpConstantComposite when vectorizing in SPIR-V.
Previously, when we vectorized scalars, we would not place them in the
constant buffer, so we could emit simple vectors like (0,0,0) or (1,1,1)
more than once. Now, we use `writeConstructorSplat` to vectorize, which
knows how to write constants.

d0234ba3bf Move backend-specific error tests out of errors/ test folder.
These tests only generate an error in the SPIR-V or GLSL backends. We
will soon enforce that everything in errors/ must actually fail to
compile.

e051cd35e4 Disallow 'binding' and 'set' on push constants
These aren't allowed on push constants (it's a validation error now), so
we at least catch it in the SPIRV generator and emit an error. Fixed two
places where we were breaking this rule when automatically adjusting
layouts for interface blocks.

43ac7e6315 Fix parsing error with SPIR-V negating a uint.
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.

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.

191b4e2a00 Enable proper testing of matrix-scalar ops.
Now that the various Metal and SPIR-V bugs have been shaken out, we can
enable these tests. Knock on wood.

29b44fc226 Add SPIR-V test for matrix-op-scalar math.
This is a clone of the Metal test. (This can be moved into shared/ and
enabled as a real test once the codegen is fixed.)

At present, this test generates broken code; everything is writing an
SpvOpMatrixTimesScalar opcode regardless of the actual operation being
performed.

2a4c0fbdca Improve memory layout handling in SPIRV generator
Added asserts that verify we don't try to emit the same struct or array
with two different memory layout rules. Some code paths were failing to
inspect the associated variable, leading to incorrect errors about the
attached offsets of members.

Added a test case that triggered that error, and also triggers the new
asserts.

Then, fixed the underlying cause: writing out the struct definition as a
side effect of accessing a member in getLValue().
