afaict the perf surprises associated with:
https://skia-review.googlesource.com/c/skia/+/334417 (Remove SkBaseDevice::flush)
were bc Ganesh resolves MSAA buffers for SkCanvas::flush but doesn't do so for GrDirectContext::flush.
Where possible this CL switches SkCanvas::flush to SkSurface::flush (which will also resolve MSAA buffers) so that when https://skia-review.googlesource.com/c/skia/+/334417 relands there should not be any performance surprises.

As written today we push two sets of the paint color uniforms (4 floats
each set, 8 total): the blitter pushes one unpremul set itself to pass
to shaders that would like to use them, and when there's no shader, we
synthesize an Color4Shader using the paint color that ends up pushing
the other set, this time premul.
When the paint color is opaque there's no difference between these two
sets of uniforms, and when not, well, it's just a few cheap *hoisted*
multiplies to go from that first unpremul set to premul. So no real
pressing need to push those premul values at all.
This CL adds a new SkShaderBase subclass PaintColorShader used only for
that case where we're synthesizing a shader from the paint color, and
just does what I've described, `return premul(paint);`.
I really only did this because I've been poking around in the debugger
looking for some other bug and noticed the duplicate values in the
uniforms array. I expect no real-world effect from this CL except fewer
uniforms to look at in the debugger.

This simplifies the shader down to only 2 states:
- use the explicit SkSamplingOptions it has
- look at the paint's enum
Ultimate goal: remove the paint's enum
Middle goal: remove references/reliance on the enum downstream
in the code. This CL is partway on that.
Possible next step: retool legacy bitmapprocshader to explict work with
FilterOptions (not SkFilterQuality) -- so that eventually the enum
appears *only* when we see the paint, and can immediately turn it
into FilterOptions.
Another next-step: add SkSamplingOptions to drawImage/drawImageRect,
to make it easier to update call-sites to not rely on the paint.

We were always pre-loading the fragment and vertex modules, but deferred
loading all others. Those two take up about 300 KB of heap. Now, all
modules are deferred, so compiler instances that don't need them (like
the one used for runtime effects) are much smaller.
Now that we can get better fine-grained numbers, added two more
benchmarks, to track actual baseline usage, plus the usage in the two
most likely configurations.

This allows swizzle removal to apply in more cases; in particular, we
can now optimize away extra swizzles caused by zero/one swizzle-
components quite effectively.
The "trivial expression" code was lifted from the inliner. Some subtle
changes in trivial-expression determination affect the inliner's results
in boring, non-meaningful ways. In particular, multi-argument
constructors containing all-constant values are now considered trivial,
whereas previously only single-argument constructors made the trivial-
ness cut. This allows the inliner to propagate some values that it
wouldn't have before.
