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.

Early returns can cause the inliner to generate suboptimal code. We
control our built-ins, so let's avoid them where we can.
Patterns like this challenge the inliner:
if (x) return y;
return z;
But this can be replaced by equivalent code that inlines better:
return x ? y : z;
Or, if a ternary can't be used, this also does a better job:
if (x) return y;
else return z;
In several cases, this allows the inliner to avoid generating a
do-while(false) block for control flow.

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.

At this point, the remaining uses of deprecated clip ops are all in unit tests that
specifically test a clip stack (raster, conservative, or skclipstack) that specifically
supports expanded clip ops and the tests are testing those operations. They can remain

SkSL::Swizzle objects never represent constant swizzles - they are
directly converted to IR that represents a small sub-tree, up to the
most complex case of:
Swizzle(Constructor(Swizzle(BaseVector), Literals, ...))
GLSL was the only backend that handled arbitrary complex swizzles
correctly in all cases - this change basically moves that logic into the
IR generator, subsumes the (similar) handling of scalar swizzles that
was there, and simplifies the algorithm so that it's all procedural (not
hard-coded based on bit-patterns).

`fBuiltinFMASupport` is now true on both, and

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

These tests cover all the new Q14x2 ops.
As usual, left myself a few TODOs...
While working on this, I uncovered a little subtly about the blend
instructions we use to implement Op::select... unlike the platonic
(cond & true_val) | (~cond & false_val)
the hardware istructions are not bitwise! Each of the fancy blend
instructions like vblendvps or vpblendvb has a fundamental granularity
larger than a bit (4 bytes for vblendvps, 1 byte for vpblendvb). If
you're using a mask with a granularity of say, 2 bytes, you need to be
using something with equally fine granularity --- bitwise is ok,
bytewise is ok, 2-byte-wise is ok, but 4-byte-wise isn't.
Took a quick survey, and the Op::select we're using for x86 and ARM
JITs are both bytewise, so I think they're fine. Would have to think
a bit about LLVM, but these unit tests should at least fire if it were
wrong. The skvx if_then_else() I've been using in the interpreter has
been 4-byte-wise, but I'm refining that down to 1-byte-wise with

link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:
1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
- If you look from patchset 5 and earlier, the define defaults to on
so I can test it on the bots, etc. but the plan will be for it to
default to off when this lands so it's only running on unit tests.
Then in a follow up, I'll turn it on for our bots but keep it off in
chrome and android. If everything looks good, chrome can then be
turned on. There is a more extensive migration plan for android
because of the expanding clip ops, but that is covered at the end of
the overview doc.
2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
- Once GrClipStack is enabled everywhere, it means GrReducedClip and
GrClipStackClip can be deleted, so I'm not too worried about sharing
code between the two. A lot is already shared through the use of
GrSWMaskHelper and GrStencilMaskHelper.
- SkClipStack and SkClipStackDevice are still used by the PDF and SVG
backends, so they aren't necessarily deletable.
3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
- When a new save record is pushed on the stack, older elements are
inactive. This means they cannot be modified, since they may need to
be activated again when the current save is popped off the stack.
However, they can still affect the clip during application.
- When a new element is pushed on the stack, older elements may be
invalidated. This means they don't need to be considered any more
because they are redundant with the new clip shape (e.g. nested round
rect clips only have to keep the innermost valid).

This feels pretty awkward, but it's the most straightforward way I see
to do this without Yet Another Canvas Subclass.

Takes SkYUVAPixmaps. Still implemented in terms of SkYUVAIndex[4]
internally.
Replace all internal use cases except wacky_yuv_formats.
Takes GrRecordingContext rather than GrContext.
SkVideoDecoder updated to take GrRecordingContext.

GN lists both the .cpp and the .h as generated outputs, so if they don't
exist, Ninja assumes we need to rebuild the tests every time we compile.
