(1) Performance is better or stays the same.
(2) Code is split into functions (RasterPipeline-ish
design). IMO, it's not really more or less readable.
But I think it's now much easier add capabilities,
apply optimizations, or do more refactors. Or to
actually use RasterPipeline. I help back from trying
any of these to try to keep this CL sane.

These files are now so badly misnamed that it is causing problems.
The original files are kept as shells until Chromium and PDFium can
be updated. After Chromium and PDFium builds are updated, the old
files will be removed and the cmake and bzl builds will be updated.

Lessons learned
1. ImageShader (correctly) always compresses (typically via PNG) during serialization. This has the surprise results of
- if the image was marked opaque, but has some non-opaque pixels (i.e. bug in blitter or caller), then compressing may "fix" those pixels, making the deserialized version draw differently. bug filed.
- 565 compressess/decompresses to 8888 (at least on Mac), which draws differently (esp. under some filters). bug filed.
2. BitmapShader did not enforce a copy for mutable bitmaps, but ImageShader does (since it creates an Image). Thus the former would see subsequent changes to the pixels after shader creation, while the latter does not, hence the change to the BlitRow test to avoid this modify-after-create pattern. I sure hope this prev. behavior was a bug/undefined-behavior, since this CL changes that.

No one appears to be using the default 2.2.
This makes SK_GAMMA_SRGB the default / a no-op, which seems more realistic.
Chrome's explicitly setting SK_GAMMA_EXPONENT or SK_GAMMA_SRGB.
We set Android platform explicitly to 1.4.

Most visibly this adds a macro SK_RASTER_STAGE that cuts down on the boilerplate of defining a raster pipeline stage function.
Most interestingly, SK_RASTER_STAGE doesn't define a SkRasterPipeline::Fn, but rather a new type EasyFn. This function is always static and inlined, and the details of interacting with the SkRasterPipeline::Stage are taken care of for you: ctx is just passed as a void*, and st->next() is always called. All EasyFns have to do is take care of the meat of the work: update r,g,b, etc. and read and write from their context.
The really neat new feature here is that you can either add EasyFns to a pipeline with the new append() functions, _or_ call them directly yourself. This lets you use the same set of pieces to build either a pipelined version of the function or a custom, fused version. The bench shows this off.
On my desktop, the pipeline version of the bench takes about 25% more time to run than the fused one.
The old approach to creating stages still works fine. I haven't updated SkXfermode.cpp or SkArithmeticMode.cpp because they seemed just as clear using Fn directly as they would have using EasyFn.
If this looks okay to you I will rework the comments in SkRasterPipeline to explain SK_RASTER_STAGE and EasyFn a bit as I've done here in the CL description.

Adds the ability for GLInstancedRendering to use
glDrawElementsInstanced when glDrawElementsIndirect is not supported.
The only remaining 3.1 dependency now is EXT_texture_buffer.
Also moves the cap for glDraw*Instanced out of GrCaps and into
GrGLCaps.

This takes advantage of the fact that all the compilers we use that
support NEON implement it with their own vector extensions. This means
normal things like c = a + b work on the underlying vector types already.
Odd instructions like min or saturated add need to stay intrinsics.
Also, rearrange functions to a more consistent order.

In order to remove this define it will first need to be defined in
Chromium. However, doing so causes redefinition warnings as errors.
Only define this macro if it is not already defined to avoid this.
