Two (related) changes here:

1) Our older iOS devices failed our sRGB tests, due to precision issues
with alpha. At this point, we only test on iPadMini 4, and that appears
not to have any problems.

2) iOS devices still don't have the sRGB texture decode extension. But,
some clients have no interest in mixing legacy/color-correct rendering,
and would like to use sRGB on these devices. This GrContextOptions flag
enables sRGB support in those cases.

Adjust the test code to produce sRGB capable contexts on these devices,
but only for configs that have a color space. (See comment).

SkColorSpaceXform bug fixes

(1) Clamp properly!

Finally came to this realization: clamping in the
store functions (after gamma encoding) is ridiculous.
It is impossible to know how to clamp premul values
to alpha when they are already gamma encoded.

I've moved the clamp out of the store function.
Whew, this actually makes the code look simpler.

And I expect this to fix some buggy images on Gold!

(2) Correctly handle the memcpy() case.

Looks like this only ever worked for RGBA inputs,
never got updated when we added BGRA inputs.

This probably flew under the radar because the
clients are smart enough to avoid performing a
color xform altogether when the color spaces
match.

Make gather() look and work more like load().

They're really similar, so let's make them look that way.
Finally use mask load, mask store, and gather instructions for 8888.

We avoid mask load and store when tail == 0.  It's faster (one memory load instead of two) and a cheap test.
For gather, the intrinsics make it look like we could do the same, but it really all boils down to the same masked instruction in the end.

There's probably a better way to implement mask() with math instead of memory loads, but this works for now.

Make GrMemoryPool play nice with bucketing allocators.

Some memory allocators have very coarse size buckets, so for example on
Android (jemalloc) an attempt to allocate 32 KiB + 1 byte will end up
allocating 40 KiB, wasting 8 KiB.

GrMemoryPool ctor takes two arguments that specify prealloc / block sizes,
and then inflates them to accommodate some bookkeeping structures. Since
most places create GrMemoryPools with pow2 numbers (which have buckets in
most allocators) the inflation causes allocator to select next size bucket,
wasting memory.

This CL makes GrMemoryPool to stop inflating sizes it was created with, and
allocate specified amounts exactly. Part of allocated memory is then used for
bookkeeping structures. Additionally, GrObjectMemoryPool template is provided,
which takes prealloc / block object counts (instead of sizes) and guarantees
that specified number of objects will fit in prealloc / block spaces.

simplify

This file is getting complicated.  We're still in early days and I want to keep it nimble and easy to refactor.

Simplifications:
   - go back to one stage function type, packing x and tail together in one size_t
     (x_tail = x*N+tail; x = x_tail/N, tail = x_tail%N, all cheap for power of 2 N);
   - all stages call next(), ending in just_return;
   - stop coddling MSVC with kIsTail.

These simplifications should all make things a little slower, some only when using subpar compilers.
On a positive note, this should cut code size by about half.

Apparently we had issues with this on Qualcomm over 3 years ago.

Today it works fine on a Nexus 6P. If we still need this on some devices we should add back a narrower filter.

Split srgb out of accum stages.

By stashing the scales in the context (i.e. on the stack), we can free up enough registers to really simplify how the bitmap sample stages interact.

Nearest neighbor is straightforward now: just call the appropriate gather_ function, and you're done.  The source pixels end up in the source registers.  If they're sRGB encoded, follow up with from_srgb_s

To bilerp, we bracket those 1 or 2 gather+from_srgb_s stages with a stage setting up each corner (x += dx, y += dy, save off scale) and a stage that accumulates into the d-registers (load saved scale, dr += scale * r, etc.).  When all the samples are accumulated, copy the d-registers into the s-registers.

from_srgb_d and to_srgb are lightly sketched here and will be used in the next CL, where I apply this same factoring to non-bitmap loads and stores.  This is a little tricky, because we don't actually have a float->float to_srgb yet.

Fix unpremul stage.

The existing invert() logic explodes when a == 0.

Less terribly, invert() also does not turn 1.0f into 1.0f, so we now use a float divide.  This will cause a small diff in the matrix color filter GM due to increased unpremul precision.

There's an alternative to try if this stage turns out to be speed critical:
   auto scale = (a == 0.0f).thenElse(0.0f,
                                     a.invert() * (1.0f / SkNf(1.0f).invert()));

The (1.0f / SkNf(1.0f).invert()) bit there is a constant, scaling a bit to make 1.0f produce 1.0f.

Some simple pipeline refactoring.

This is a batch of little tweaks that all preserve the existing logical behavior:
  - rename dst to move_dst_src to parallel move_src_dst
  - remove unused swap_src_dst
  - move swap_rb up with the other utility stages
  - factor out from_8888() to parallel from_565() and from_4444()
  - factor out gather() from the accum_* stages

This changes the order of the math in accum_8888[_srgb] ever so slightly, from (scale * C) * (1/255.0f) to scale * (1/255.0f * C).  It causes a few pixel diffs, but nothing noticeable.  This makes the 8888 bilerp logic consistent with the other formats, which all convert to [0,1] float first before being scaled.
