GrThreadSafePipelineBuilder is the generic, base object the
GrContextThreadSafeProxy will hold. Each backend will create a
backend-specific version that is shared between the direct context
and the (possibly many) utility contexts.
Right now GrThreadSafePipelineBuilder just holds the pipeline
creation stats. Relatedly only GrGLGpu::ProgramCache and
GrVkResourceProvider::PipelineStateCache currently derive from
the new class (since they are the only backends that generate
pipeline stats).

In http://review.skia.org/375776, an optimization was added to the
Inliner, causing it to skip generation of unnecessary temporary
variables. The fuzzer immediately discovered a flaw in this logic: the
"unnecessary" variable was actually used in the rare case that a
function failed to actually return a value. The inliner didn't detect
this case. Of course, this isn't a valid program either, so now we
report the error and cleanly fail.

This adds Analysis::IsConstantExpression, to determine if an expression

This fixes 10837 - previously you could initialize a const variable with
a non-constant expression, and we'd emit GLSL that contained that same
pattern, which would fail to compile at the driver level. That should
not be possible any longer.

This splits switch() construction into two stages.
- One version of Make takes an array of case-values and case-statement
lists, and is responsible for reporting errors if the case-values are
not unique or are improperly typed. This is what the IR generator or DSL
will start with on its first encounter with the switch statement.
- The other version of Make takes an array of already-processed
SwitchCases and can assume the invariant that they're all correctly-
typed with unique values. This is what we will have when a statement
is inlined or otherwise cloned. (We still assert this invariant, for
correctness' sake, but in release mode we assume it.)
This CL doesn't perform any optimizations at Make time yet; it does work
equivalent to how `switch` works in the IR generator today. It does
improve duplicate case-label checking slightly; duplicate case labels
are now reported, and duplicate `default:` labels are detected.
(Multiple `default` labels won't pass the parser, but they can be
constructed in DSL.)

The optimizer now properly recognizes all types of exits from a switch

to be considered when determining the exit path from the switch.
Previously, dead code elimination was hiding the effects of this bug
from us, but it meant that an optimized switch had the potential to
generate lots of worthless IR nodes which then needed to be detected and
eliminated by the CFG. In particular, this affected the enum form of
blend, causing a catastrophic amount of extra work to be done.

When we detect a static switch, the optimizer finds the matching switch-
case and eliminates all the other switch-cases. It handles case
fall-through by scanning forward and looking for an unconditional break.
However, the inliner has an interesting quirk--it can replace `return`
statements inside of a switch with `continue` statements, since the body
of the inlined function has been wrapped with a for-loop to allow for
early exits. The optimizer does not recognize these continue statements
as exits from the switch (although they certainly qualify), so it
treats continues as fallen-through and keeps emitting switch-cases.
The dead-code elimination pass was actually doing us a favor here and
eliminating the excess code later. A flag was added to disable DCE in
order to reveal the problem in a test.

This warning was originally a stand alone clang warning, not part of
'all' or 'extra', which had false positives. These false positives were
particularly accute when a container's iterators are proxy iterators.
Unfortunately the warning was moved into 'all' before being fixed.
After this became apparent, the warning was modified and split up, but
not before it was shipped in Clang 10 and XCode 11. It appears the fixed
version of the warning is in Clang 12 and XCode 12. Until the older
compilers are no longer supported, disable the warning.
This explicitly keeps the useful range-loop-construct warning which is
part of the range-loop-analysis. The range-loop-bind-reference part is
disabled.

There are two forms. Swizzle::Make supports components XYZW only;
Swizzle::MakeWith01 also supports the 01 components, and restructures
the zeros and ones into a constructor (as IRGenerator::convertSwizzle
has historically done). This means that once we are past the initial
IR generation stage, and we know that the 01 components have been
eliminated, we can avoid the extra 01-handling logic and just call
Swizzle::Make directly. This isn't a huge deal but it means that call
sites like the inliner can avoid some extra work that will never happen.

Surprisingly, this error is actually caught by our parser, which
interprets the default label in a unique way. From the parser comments:
"Requiring default: to be last (in defiance of C and GLSL) was a
deliberate decision. Other parts of the compiler may rely upon this
assumption."
The comment is true--we don't check for duplicate default switch-case
labels anywhere else in the code, just here in the parser.
We rely on this, so we should have a test for it.

Add sources_for_tests to optional targets. If set, a taget_name_tests
source_set will be created which matches the target_name target except
that the sources are the sources_for_tests.
This allows the tests for these targets to be obviously related to the
target they test instead of having to diplicate the logic of the
optional's enabled predicate in the test target. The test target can
just directly depend on the optional test target in the same way it can
depend directly on module tests.
This was motivated by the existence of two such tests and the need to
soon introduce another (for CoreText).
