This resolves the following TODO block:
TODO(johnstiles): the skslc standalone caps bits do not enable
do-while support, so this test does not actually perform as
described; the `returny` function is not inlined at all. This will
be fixed when customizable caps-bit support is added to the golden
tests.

We were allowing these ops on floating point types. The resulting GLSL
would fail to compile. We also allowed >>= and <<= on vectors (but not
any of the other bitwise ops).
The newly added unit tests were failing (eg, not catching errors). New
results are correct.

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.

This will allow us to write skslc-based golden tests that deviate from
the standalone skslc settings.
This CL provides six options; more will be added as necessary.
- Default (caps)
- UsesPrecisionModifiers (caps)
- Version110 (caps)
- Version450Core (caps)
- ForceHighPrecision (settings flag bit)
- Sharpen (settings flag bit)

A handful of simplifications were made, but these hew very close to the
original tests and are intended to cover the exact same ground. The
remaining unconverted tests depend on non-default caps bits and will
be updated once caps handling in skslc is fully landed.

`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.

Our lack of proper caps-bits controls in skslc affects the outcome of
one test: "InlinerWrapsEarlyReturnsWithDoWhileBlock" does not actually
emit the do-while block because the standalone caps bits don't enable
do-while support. This will be fixed in a followup CL that adds caps-bit
support to our tests.
A few tests were renamed for consistency, a few were simplified slightly
and one test was removed because it was simply redundant (there was a
second test that covered the exact same ground as
`ForWithReturnInsideCannotBeInlined`).

The following conditions lead to the error:
- A pair of nested functions, both of which must be inlined.
- Both inlined functions create a variable with the same name.
- The outer function passes its variable to the inner function.
- The initialization of the inner variable uses the value from the outer
variable.
- The inner function does not mutate the variable, use it as an out-
parameter, or otherwise cause it to receive a temporary copy.
When all these conditions are met, both variable declarations are
inlined as-is without performing any name salting, because it's
seemingly safe to do so. The name overlap issue is not considered in the
safety checks. Inlined variable declarations are not subject to name
salting but they should be; I suspect other adversarial examples could
be crafted as well where unhandled name overlap leads to errors.

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.
