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.

This fixes the perf bot crashes from https://skia-review.googlesource.com/c/skia/+/317209
and removes a few other instances of kReplace_ClipOp that are equivalent to the
still supported SkClipOp::kIntersect op. Other than the benchmark case, the GPU
clip stack wasn't hitting these cases but they do need to be updated when the deprecated
ops are fully removed.
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
until we remove full support.

Implement min and max using if_then_else(y<x,...) on vectors
rather than recursing to std::min/std::max applied to scalars.
But actually, factor out and use naive_if_then_else(), which Clang can
reason through better than it can our specialized if_then_else(). This
lets every min() or max() I've looked at compile down to ideal codegen,
vmaxps, vpminsw, etc, where if you use if_then_else() you'd see the
literal comparison and blend as written.
I've been looking at q14x2 codegen in the interpreter, and most things
were already good, unexpectedly even uavg_q14x2. The biggest surprise
was how bad the min/max codegen was, and looking back, even the min_f32
and max_f32 codegen is super bad. This CL fixes all that, leaving us
with the ideal codegen using the specific instruction you'd want,
replacing a giant mess of code that recursed down to scalars.
mul_q14x2 is still bad, but an easy follow up.

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).

This will help our skslc-based unit tests generate the same results as

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
https://skia-review.googlesource.com/c/skia/+/317170.

The default implementation of if_then_else is logically bitwise,
(cond & true_val) | (~cond & false_val)
The existing skvx specializations work only for 32-bit lanes, but we can
easily make them work for any type where the whole vector is the right
size by reducing the granularity down to byte level.
Existing code using 32-bit values and 0xffff'ffff or 0x0000'0000 masks
will continue to work the same. But this now lets us use, e.g. 16-bit
values with 0xffff and 0x0000 masks, or even things like 32-bit values
and a mask like 0xff00ff00, selecting byte by byte.
We can't go any lower without falling back on the generic bitwise
implementation, so we'll have to settle for not getting to use a mask
like 0x0f0f0f0f.

Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing
This is the new clip stack that will replace GrClipStackClip. The doc
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

This makes our behavior more consistent with drawRect (where we always
sort rects). It also makes it more consistent between CPU and GPU. (CPU
used a technique to implement rect clipping that allowed for unsorted
rects, but GPU's clip stack would reject them as empty).

This is a 32-bit pair of Q14 (signed 1.14 fixed point) values.
Q14 * Q14 is (x*y + 0x2000)>>14 but we'll do it as
((x*y + 0x4000)>>15)<<1 to allow use of vpmulhrsw.
Somewhat awkwardly this approximate math does not preserve x*1.0 == x,
e.g. 0x0001 * 0x4000 = 0x0002, not 0x0001. I'm unsure if we'll care.
x*0.0 == 0.0 does always hold, and 1.0*1.0 == 1.0.
Most other operations are normal 16-bit operations.
TODO:
- implmement in interpreter
- unit test
- constant propgation and strength reduction
- implement in JIT
- effect/blitter hooks enough to demo
- thorough effect/blitter support

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.

On Windows, the process output contains CRLF sequences. Calling
splitlines() recognizes those (Python universal line endings), so we get
a list of the output lines. Joining those with '\n' produces a string
that just has LF. (We add another one, so we still end the file with a
newline). Because we've opened the file in binary mode, the resulting
files now look the same, regardless of OS.

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`).

Add a slew of 16-bit instructions for experiments.
I want to try a fixed-point path through SkVMBlitter, continuing to
represent geometry with F32, but color channels in 16 bits, with several
possible representations:
- unorm8 lowp like SkRasterPipeline (0 -> 0.0, 0x00ff -> 1.0)
- 15-bit SkFixed15 fixed-point (0 -> 0.0, 0x8000 -> 1.0)
- 14-bit signed fixed-point (0 -> 0.0, ±0x4000 -> ±1.0)
I'm leaning towards the 14-bit version for being able to hold a good
range of temporary values in [-2,2), or perhaps even a 13-bit analog for
even a little more safety range. Mostly something new to try.
Most of these instructions are pretty obvious, with notes on a few:
vpavgw is an unsigned (x+y+1)>>1, and is useful for converting
unorm8 up to Q14. There are a couple ways to do this pretty well,
and using vpavgw is the best, and uses the fewest instructions:
A) (x << 6) + ( x >> 2) + (x == 255) // Ok approx.
B) (x << 6) + ((x+1) >> 2) // Better approx.
C) vpavgw(x << 7, x >> 1) // Perfect math!
The best good reverse math I've found is (x >> 6) - (x > 16319).
vpmulhrsw is the key to the whole thing as usual, letting us do
16x16->16-bit multiplies. An SkFixed15 multiply is vpmulhrsw
followed by vpabsw (also added here), and a Q14 multiply is
vpmulhrsw followed by a simple <<1.
I've added both signed and unsigned min and max. Not entirely
sure they'll all be used, but I do have my eye on vpminuw as a
single-instruction clamp to [0,0x4000] ~~> [0.0,1.0], treating
any negative Q14 as very large unsigned.
