Mike points that the the ulps compares
rank high in path ops profiles. The
check for finite scalars is rarely
required.
Call it less by:
- specializing _pin version of compares
- checking for 0 divides up front
- handling failing cases before comparing
- casting float to double before adding

This is mainly warmup for an AVX2 version.
The machine I'm typing this on just doesn't support AVX2.
This strategy should translate easily down to SSSE3 and SSE2.
Xfermode_SrcOver: 2.73ms -> 2.62ms (0.96x) (That's Color32.)
Xfermode_SrcOver_aa: 3.48ms -> 3.09ms (0.89x) (That's BlitMask_D32_A8.)
AA text blits (text_16_AA_{88,FF,WT,BK}) show speedups in the range of 5 to 20%.
Unlike previous versions of this code, all the div255() are exactly (x+127)/255.
This won't fix any major bugs, but it does correct our bias in the middle.
There will be many diffs, all minor.
I've punted for now on pmaddubsw for lerping. I do intend to try that,
but I want this (relatively simple) code as my basis for comparison.

These were originally used to compare to the old implementation of
subset decoding in SkImageDecoder. The old implementation has been
removed, and they do not provide useful information that is not
covered by the BitmapRegionDecoderBenches.
This will greatly speed up some of our infra bots, which spend a lot of
time decoding interlaced PNGs repeatedly (thanks to
SubsetTranslateBench).

When the default framebuffer is wrapped in a device for rendering we don't get a GrTexture. This CL adds a copy to a temporary texture in this instance so the rest of the Ganesh pipeline can continue on as usual.

This is more general than checking for __linux, __FreeBSD__, etc. (In
principle we could remove some of the existing checks such as
__FreeBSD__, but I have not tried that so far.)
In particular, it allows Skia to build with the NaCl or PNaCl
toolchains, which is something we would like for Mojo.

Given the autovectorization we've seen, I wouldn't expect big speedups
from this, but it does give us a point of control over what's going on.

Epsilon bias to keep bitmap sample rounding consistent with geometry
rounding.
Also update the GM to draw an outer border + drop uninteresting

Add extended config specification form that can be used to run different
gpu backend with different APIs.
The configs can be specified with the form:
gpu(api=string,dit=bool,nvpr=bool,samples=int)
This replaces and removes the --gpuAPI flag.
All existing configs should still work.

Try to fix intermittent GrAutoLocaleSetter crashes on Windows.
The string returned by setlocale() is only valid up to
next setlocale(), so it can not be fed to setlocale().
Also, libraries such as ANGLE might call setlocale when
inside a callstack containing GrAutoLocaleSetter. This
would render the old locale pointer invalid.
