Reason for revert:
942930d (included in this roll) introduced a 140 kB sizes regression in
libskia.so. Please investigate and reland if this regression is necessary.
Original issue's description:
> 565 support for SIMD xfermodes
>
> This uses the most basic approach possible:
> - to load an Sk4px from 565, convert to SkPMColors on the stack serially then load those SkPMColors.
> - to store an Sk4px to 565, store to SkPMColors on the stack then convert to 565 serially.
>
> Clearly, we can optimize these loads and stores. That's a TODO.
>
> The code using SkPMFloat is the same idea but a little more long-term viable, as we're only operating on one pixel at a time anyway. We could probably write 565 <-> SkPMFloat methods, but I'd rather not until it's really compelling.
>
> The speedups are varied but similar across SSE and NEON: a few uninteresting, many 50% faster, some 2x faster, and SoftLight ~4x faster.
>
> This will cause minor GM diffs, but I don't think any layout test changes.

This change is motivated by a recent switch in how chromium handles
<video> color spaces, making rec709 more commonly used. This will
allow video -> canvas copies to take the fast GPU path when we're using
709, just as we do with 601 and jpeg.

The gm output on different font platforms is so different
that comparing images in Gold has little value. Separate the
images by appending platform information to the gm name to
group somewhat similar images together.
Note that this does not attempt to make sure that all images
generated by Gold are nearly pixel identical; it only reduces
the number of nonsensical comparisons.

The code using SkPMFloat is the same idea but a little more long-term viable, as we're only operating on one pixel at a time anyway. We could probably write 565 <-> SkPMFloat methods, but I'd rather not until it's really compelling.
The speedups are varied but similar across SSE and NEON: a few uninteresting, many 50% faster, some 2x faster, and SoftLight ~4x faster.
This will cause minor GM diffs, but I don't think any layout test changes.

This updates Ganesh's bleed avoidance check to handle the case where the
sample location may be outside of the rect geometry but used because it
partially covers the pixel.

Now that SK_SUPPORT_LEGACY_XFERMODES is unused, tons of code becomes dead.
Nothing is needed in opts/ anymore for x86.
We still do runtime NEON detection, which just duplicates Sk4pxXfermode.

The normalize routine in SkPoint3 is very robust. However, for simple
lighting cases we prefer speed over robustness. This fixes a perf
regression in smoothness.tough_filters_cases.

Blacklist all image tests on msaa. We do not run them anyway (since
they will not do anything interestingly different from drawing to the
raster backend) - we early exit from Src::draw(), but we still need to
create a render target that matches the size of the image (when not
blacklisted).
Remove the more specific blacklist of a particular image, which is
covered by this one.

Motivation:
- perf win for clients that overwrite the surface after a snapshot.
- may allow us to eliminate SkDeferredCanvas, as this was its primary advantage.
