The refactoring breaks off A2B0 tag support into a separate
subclass of SkColorSpace_Base, while keeping the current
(besides CLUT) functionality in a XYZTRC subclass.
ICC profile loading is now aware of this and creates the A2B0
subclass when SkColorSpace::NewICC() is called on a profile
in need of the A2B0 functionality.
The LabPCSDemo GM loads a .icc profile containing a LAB PCS and
then runs a Lab->XYZ conversion on an image using it so we can
display it and test out the A2B0 SkColorSpace functionality,
sans a/b/m-curves, as well as the Lab->XYZ conversion code.

This is only useful in the rare case that the dst does not
fall into one of our main paths.
But it's a good optimization, since this does happen,
and typically, the dst won't change.

It will now reside in SkColorSpace_Base. Future work for SkColorSpace
will cause this function to not be desirable or sensible to call on
all SkColorSpaces. Call sites were changed to make a kSRGBLinear_Named
instead of kSRGB_Named -> makeLinearGamma() (the majority of cases),
and if that was not possible, SkColorSpace_Base::makeLinearGamma()
was called instead.

This is handy now, and becomes necessary with fancier backends:
- most code can't speak the type of AVX pipeline stages,
so indirection's definitely needed there;
- if the pipleine is entirely composed of stock stages,
these enum values become an abstract recipe that can be JITted.

This lets them pick up runtime CPU specializations. Here I've plugged in SSE4.1. This is still one of the N prelude CLs to full 8-at-a-time AVX.
I've moved the union of the stages used by SkRasterPipelineBench and SkRasterPipelineBlitter to SkOpts... they'll all be used by the blitter eventually. Picking up SSE4.1 specialization here (even still just 4 pixels at a time) is a significant speedup, especially to store_srgb(), so much that it's no longer really interesting to compare against the fused-but-default-instruction-set version in the bench. So that's gone now.
That left the SkRasterPipeline unit test as the only other user of the EasyFn simplified interface to SkRasterPipeline. So I converted that back down to the bare-metal interface, and EasyFn and its friends became SkRasterPipeline_opts.h exclusive abbreviations (now called Kernel_Sk4f). This isn't really unexpected: SkXfermode also wanted to build up its own little abstractions, and once you build your own abstraction, the value of an additional EasyFn-like layer plummets to negative.
For simplicity I've left the SkXfermode stages alone, except srcover() which was always part of the blitter. No particular reason except keeping the churn down while I hack. These _can_ be in SkOpts, but don't have to be until we go 8-at-a-time.

In some build configurations (I think, GN, GCC 6, Debug) I get a warning that i is used unintialized. This likely has something to do with GCC correctly seeing that the SkTCast construction there is illegal aliasing, and perhaps thus "doesn't happen". Might be that if the SkTCast gets inlined, it decides its implementation is secretly kosher, and so Release builds don't see this. None of this happens with the GCCs we have on the bots... too old?
Instead use memcpy() here, which is well defined to do what we intended.

We used to step at a 4-pixel stride as long as possible, then run up to 3 times, one pixel at a time. Now replace those 1-at-a-time runs with a single tail stamp if there are 1-3 remaining pixels.
This style is simply more efficient: e.g. we'll blend and lerp once for 3 pixels instead of 3 times. This should make short blits significantly more efficient. It's also more future-oriented... AVX+ on Intel and SVE on ARM support masked loads and stores, so we can do the entire tail in one direct step.
This also makes it possible to re-arrange the code a bit to encapsulate each stage better. I think generally this code reads more clearly than the old code, but YMMV. I've arranged things so you write one function, but it's compiled into two specializations, one for tail=0 (Body) and one for tail>0 (Tail). It's pretty tidy.
For now I've just burned a register to pass around tail. It's 2 bits now, maybe soon 3 with AVX, and capped at 4 for even the craziest new toys, so there are plenty of places we can pack it if we want to get clever.

Today if you use the simple SK_RASTER_STAGE interface to build a pipeline, each stage you add calls into a next stage. The last stage you add calls into a special backstop stage JustReturn that, well, just returns, ending the pipeline.
This adds last(), which cuts that last stage off the pipeline. Instead, the stage you add using last() returns directly, ending the pipeline itself without jumping into JustReturn.
This reduces the overhead of using the pipelined version of SkRasterPipelineBench from ~25% to ~20% on my desktop.
Also, add docs.

It was not a fan of this (blatant) aliasing.
I suspect this best_non_simd_srcover_srgb_srgb() function has several
other aliasing issues that use undefined behavior, but this is all it's

The SkFontData type is not exposed externally, so any method which uses
it can be updated to use smart pointers without affecting external
users. Updating this first will make updating the public API much
easier.
This also updates SkStreamAsset* SkStream::NewFromFile(const char*) to
std::unique_ptr<SkStreamAsset> SkStream::MakeFromFile(const char*). It
appears that no one outside Skia is currently using SkStream::NewfromFile
so this is a good time to update it as well.
