Hopefully I can start to knock off effects that need
to be converted to dst colorspace one at a time now.
My rough list is,
- paint color <----
- image shader
- sprite blitter
- gradients?
- mode color filter
- lighting color filter
- high contrast filter
- toSRGB color filter
This change cuts the diffs between 8888 and srgb from
~540 to ~500.
I left myself a note about not being able to interpret null
to sRGB at a high level yet. That'd cause a ton of 8888 diffs,
and I think SkColorSpaceXformCanvas diffs too.

We passed this iota array as an argument before because it was
generating awkward code for our object file parser to handle
(relocations, other weird things, can't quite remember).
Now that we're compiling pipeline code normally, we can make seed_shader
a normal stage again, with no special iota ctx pointer needed.

Instead of trying to carefully manage the in-gamut / out-of-gamut state
of the pipeline, let's do what a GPU would do, clamping to representable
range in any float -> integer conversion.
Most effects doing table lookups now clamp themselves internally, and
the store_foo() methods clamp when the destination is fixed point. In
turn the from_srgb() conversions and all future transfer function stages
can care less about this stuff.
If I'm thinking right, the _lowp side of things need not change at all,
and that will soften the performance impact of this change. Anything
that was fast to begin with was probably running a _lowp pipeline.

This is a no-op refactor.
It's just always surprised me that the matrix_scale_translate
stage expects [tx ty sx sy], when scales precede the translates
in the names and in both normal row-major and column-major matrix
layouts.
This switches to [sx sy tx ty], scale then translate.

struct {
float r,g,b,a;
uint32_t rgba;

so that it's trivial to load in both float and 8-bit pipelines.

The color appended here is both uniform and constant, and it's the
constantness that makes this custom append method useful over just
append(SkRasterPipeline::uniform_color, ...).
Uniform colors that are not constant have to be loaded from the pointer
each time (the caller might have changed the color out-of-band), but
constant uniform colors can be analyzed once and implemented with
specalizations like black_color and white_color.

It's easier to work on SkJumper if everything funnels through run().
I don't anticipate huge benefit from compile() without JITing,
but it's something we can always put back if we find a need.

We've been seeding the initial values of our registers to x+0.5,y+0.5,
1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines.
This CL changes that to do so only when blitting, and only when we have
a shader.
The nicest part of this change is that SkRasterPipeline itself no longer
needs to have a concept of y, or what x means. It just marches x
through [x,x+n), and the blitter handles y and layers the meaning of
"dst x coordinate" onto x.
This ought to make SkSplicer a little easier to work with too.
dm --src gm --config f16 srgb 565 all draws the same.

I think I may have cracked the compile-ahead-of-time-splice-at-runtime nut.
This compiles stages ahead of time using clang, then splices them together at runtime. This means the stages can be written in simple C++, with some mild restrictions.
This performs identically to our Xbyak experiment, and already supports more stages. As written this stands alone from SkRasterPipeline_opts.h, but I'm fairly confident that the bulk (the STAGE implementations) can ultimately be shared.
As of PS 25 or so, this also supports all the stages used by bench/SkRasterPipelineBench.cpp:
SkRasterPipeline_…
400 …f16_compile 1x …f16_run 1.38x …srgb_compile 1.89x …srgb_run 2.21x
That is, ~30% faster than baseline for f16, ~15% faster for sRGB.

A little JIT proof of concept for SkRasterPipeline, using xbyak, which is a header-only assembler. It's x86-only, but supports x86 very thoroughly, and it's very user friendly (at least as far as assembler libraries go...).

This reverts commit 2e018f548d76b0688f9873c683cffc681fec40ec.
Reason for revert: doesn't appear to have been the roll problem.

It's pretty easy to start with sound premultiplied linear floats, pack those to sRGB encoded bytes, then read them back to linear floats and find them not quite premultiplied, with a color channel just a smidge greater than the alpha channel. This can happen basically any time we have different transfer functions for alpha and colors... sRGB being the only one we draw into.
This is an annoying problem with no known good solution. So apply the clamp hammer.
These new calls on SkRasterPipeline should make it impossible to get wrong.

Bicubic is going to blow right past 48. At this point the fixed preallocation strategy is starting to look naive... at 64 we'd allocate just over 1K for every pipeline (and every compiled pipeline).

Image shaders need to do some geometry work before sampling the image colors:
1) determine dst coordinates
2) map back to src coordinates
3) tiling
Feeding (x,y) through as (dr,dg) registers makes step 1) easy, perhaps trivial, while leaving (r,g,b,a) with their usual meanings, "the color", starting with the paint color.
This is easy to tweak into something like (x+0.5, y+0.5, 1) in (dr,dg,db) once this lands. Mostly I just want to get all the uninteresting boilerplate out of the way first.

I'm not yet caching these in the blitter, and speed is essentially unchanged in the bench where I am now building and compiling the pipeline only once. This may not be able to stay a simple std::function after I figure out caching, but for now it's a nice fit.

The portable code now becomes entirely focused on enum+ptr descriptions, leaving the concrete implementation of the pipeline to SkOpts::run_pipeline().
As implemented, the concrete implementation is basically the same, with a little more type safety.
Speed is essentially unchanged on my laptop, and that's having run_pipeline() rebuild its concrete state every call. There's room for improvement there if we split this into a compile_pipeline() / run_pipeline() sort of thing, which is my next planned CL.

Original review here: https://skia-review.googlesource.com/c/2990/
Second attempt here: https://skia-review.googlesource.com/c/3064/
This is the same as the second attempt, but with the change to SkOpts_hsw.cpp left out.
That omitted part is the key piece... this just lands the refactoring.

Looks like Chrome Canary's picking up Haswell code on non-Haswell machines.
