I took a new, unprincipled approach here, which is to just mimic the
legacy code path exactly (e.g. hue_modeproc in SkXfermode.cpp).
This fixes how we handle alpha in these blend modes, and ought to be
faster by avoiding the unpremul.

Chromium usually calls SetInstance once per process. However, when run in single process more renderer threads will try to set the instance after the browser process already has done so. This allows them to fail gracefully without asserting.

This is fairly aggressive in that it will break any client
that is currently using SkImageGenerator with kIndex8.
I'm guessing that we don't have any clients doing that.

This is just a name refactor and I'm happy to delay it until we're done
with the current wave of gradient CLs. The main ideas:
- we use the "linear_gradient" stages for all gradients,
so cut the "linear" and just call them "gradient";
- remind ourselves that the 2-stop stage requires even spacing, i.e.
stops at 0 and 1. This name should harmonize with Herb's new
general evenly spaced gradient stage, currently
"evenly_spaced_linear_gradient", and after it lands and I rebase,
"evenly_spaced_gradient"
- remind ourselves which polar coordinate xy_to_polar_unit returns,
the angle.

While we're refactoring how gradients work it's going to be easier
to centralized how and when we tile.
- PS2 changed linear and radial in place to alwys clamp.
- PS3 moved tiling to the base class, where it's even harder to
screw up. Sweeps don't need but don't mind tiling.
- PS4 clamps when iff evenly spaced
PS4 has image diffs for only a few GMs that I'm not familiar with.
If its logic reads as correct to you, they may be bug fixes?

1) Only store GrColors in GrTextUtils::Paint. We still store
premul and unpremul versions, but this is slightly clearer.
2) GrTextUtils::Paint also needs info from the render target
context to linearize and transform the color to dst space.

As we have factored things, we _do_ need to map y. This matrix maps us
back from dst to src space now, but not all the way to t.
We let the subclass inject its own logic for x,y -> t.
(Linear gradients do actually still do this by modifying the first
matrix rather than appending another matrix for x,y -> t. But in
general we cannot not map y here anymore.)
