Our optimizer ignores index expressions, but has a few simplifications
that it can perform on swizzles. (Added extra code to SwizzleByIndex
which demonstrates this.)

Code like
bool4 result = val.xy01;
Will now be converted to:
bvec4 result = bvec4(val.xy, bool(0), bool(1));
Previously it tried to do this, but there isn't an implicit conversion
from int to bool, so it was silently failing and adding nulls into the
constructor:
bvec4 result = bvec4(val.xy, $coerceToBool(0), $coerceToBool(1));
This CL also cleans up some related code that I was checking while
trying to understand the nature of the error.

I realized that "DefaultSettings" as a name suffix was unclear, because
"Default" is a different settings mode from skslc running with
--nosettings.
In --nosettings mode, skslc uses "standalone" settings.

We now support building an SkSL golden output twice, once honoring the
custom #pragma settings, and once more ignoring the settings. This
allows us to see the output of the workaround technique, alongside the
"default-settings" output which should not contain a workaround.
To implement this, skslc now supports a flag: --[no]settings.
When it's set, /*#pragma settings*/ comments are honored. When it's not
set, skslc ignores the comments. compile_sksl_tests.py passes this flag
along to skslc.
This approach is not strictly limited to workarounds; the
"TypePrecision" GLSL test was also updated to use this technique.

`fBuiltinFMASupport` is now true on both, and
`fUsesPrecisionModifiers` is now false. Other mismatching flags exist,
but they are non-trivial to synchronize as they are tied to extension
strings.
This will help our skslc-based unit tests generate the same results as
our C++ unit tests did, but should not affect real-world results as
these defaults will all be overwritten in a non-testing scenario.
In practice, the `fUsesPrecisionModifiers` change is responsible for all
of the diffs below. The other flags did not change the results of any of
the currently-ported tests.

The new test files are intended to be identical to the unit tests in
every meaningful way. (Comments and formatting are not preserved
exactly.) In cases where a unit-test method contained more than one
test, multiple test files were created; in these cases, new names were
invented to match the apparent intent of each invocation.
Followup CLs will continue to migrate additional tests.

Golden SkSL outputs are intended to eventually replace the majority of
our unit tests, since they can automatically update themselves when we
change implementation details of the compiler.
If you change the compiler output without updating the Golden files, the
CheckGeneratedFiles housekeeper will be triggered. Set
`skia_compile_processors` or `skia_compile_sksl_tests` to true in your
GN args to regenerate them.
Almost all of the tests from SkSLFPTests.cpp and SkSLGLSLTests.cpp can
be migrated into separate unit-test .fp/.sksl files in a followup CL.
hcm@ has signed off on removing the copyright boilerplate preamble from
our unit test files.
