Using thread_local on iOS requires iOS 9 or greater. Chrome for iOS
now requires 13, Skia sets the minimum to 11 for test builds, and
Flutter actively does not support 8 or earlier. Dropping support for
iOS 8 in practice and moving to iOS 9 makes it possible to use
thread_local without reservations on iOS.

The important aspect is that it allows knowing the uniforms that will
be used by a set of processors without having to create ProgramImpls.
GrProcessor subclasses specify uniforms at creation time in a similar
style to how GrGeometryProcessors already specify attributes. That is,
they initialize a span of structs describing the uniform which may
contain void uniforms that are skipped. Unlike attributes, the struct
contains an offset into the processor where the data is stored.
GrUniformAggregator is used to collect the uniforms from all processors
that compose a draw and mangle their names. The ProgramImpl subclasses
query the aggregator for their uniform names when emitting code.
The old system for uniforms is left intact and only three processors,
one GP, one FP, and one XP, are updated to use the new system.
Some pieces that are missing before everything can be moved over:
-support for uniforms not owned by GrProcessor (e.g. rt-adjust)
-support for samplers
-helpers for common patterns
(e.g. GrGeometryProcessor::ProgramImpl::setupUniformColor(),
and the various matrix helpers on ProgramImpl)

This moves the swizzle domain test into the path used by the DSL so that
the error check benefits both sides. To make this possible we need to
be able to distinguish between equivalent swizzle components like x and
r, so they aren't collapsed down to the same component until the very
end.

Now that the clip atlas has been successfully migrated to
tessellation, we don't need this code anymore!

This is almost purely a query/replace CL (% the #include juggling).
The VisitProxyFunc is used by more than just the Ops and will probably
still be required in the NGA.
This is a prelude to making all the remaining GrOp-derived classes OGA-only.

Like SkColorFilter, SkShader, etc., this has a public-facing component
(SkBlender) and a private subclass (SkBlenderBase) which can be
obtained via a helper function (as_BB). At present there are no public-
facing methods, but the type needs to be exposed to be usable by the
outside world.
These classes exist for SkRuntimeEffect to subclass. The blender base
provides a `program` method with the parameters that blending will use.
