Currently, Chromium stores segmented data in a SharedBuffer and appends
to SkRWBuffer one segment at a time:
const char* segment = 0;
for (size_t length = data->getSomeData(segment, m_rwBuffer->size());
length; length = data->getSomeData(segment, m_rwBuffer->size())) {
m_rwBuffer->append(segment, length, remaining);
}
This can yield a bunch of just-above-4k allocations => wasted RAM due to
internal fragmentation.
Ideally, we'd want a SkRWBuffer::reserve(size_t bytes) API, but the
current internals don't support that trivially.
Alternatively, the caller can pass a reserve hint at append() time.

I started fixing more effects and realized I needed something like this.
Wanted to land it separately. After this, I'll add the DC's cached xform
from sRGB to AsFPArgs, so that we can easily leverage this code in more
places (mostly GrConstColorProcessor, or any effect that falls back to
that based on invariants, etc...)

- Replace SkImageBitmap with SkImageSubset
- SkBitmapKey becomes trivial for simplicity.
- SkPDFCanvas::onDraw(Bitmap|Image)Rect now clip and call
SkCanvas::onDraw(Bitmap|Image)Rect.
- SkPDFDevice::draw(Bitmap|BitmapRect|Sprite) now convert bitmap
into SkImageSubset via make_image_subset function.
- SkPDFDevice::draw(Image|Bitmap)Rect now implemented again.
- SkPDFDevice::internalDrawImage now performs image subsetting
as needed, while still deduping properly.

Haswell brought a whole slew of handy new instructions for us (AVX2, FMA, BMI1+BMI2) and also feature F16C, which came one generation earlier on Ivybridge. We work with integers often enough that we really want to target AVX2 instead of AVX, and this means it's pretty practical to ask for all those other goodies along with it.
Chrome's GN files and Google3's BUILD file will need an update, before or after this CL.

Passing in a large buffer along with a source colour space that
used a CLUT would cause apply() to read freed heap memory, or
for smaller buffers read possibly re-used stack memory.
The code previously likely lucked out due to optimizations
removing most or all of the subsequent stack allocations.

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.
