The original caching logic for sample locations wishfully assumed that
the GPU would always use the same sample pattern for render targets
that had the same number of samples. It turns out we can't rely on
that. This change improves the caching logic to handle mismatched
simple patterns with the same count, and adds a unit test that
emulates different sample patterns observed on real hardware.

Reason for revert:
I believe this is causing the Chromium DEPS roll to fail due to linux_blink_rel. Reverting for now to get the roll going again.
Original issue's description:
> Increase batching for AA fill rects.
>
> This allows batching of rects provided without a local matrix when local coords are required and when the view matrix changes.
>
> It also allows batching of rects with a local matrix with rects without a local matrix.

Adds a module that performs instanced rendering and starts using it
for a select subset of draws on Mac GL platforms. The instance
processor can currently handle rects, ovals, round rects, and double
round rects. It can generalize shapes as round rects in order to
improve batching. The instance processor also employs new drawing
algorithms, irrespective of instanced rendering, that improve GPU-side
performance (e.g. sample mask, different triangle layouts, etc.).
This change only scratches the surface of instanced rendering. The
majority of draws still only have one instance. Future work may
include:
* Passing coord transforms through the texel buffer.
* Sending FP uniforms through instanced vertex attribs.
* Using instanced rendering for more draws (stencil writes,
drawAtlas, etc.).
* Adding more shapes to the instance processor’s repertoire.
* Batching draws that have mismatched scissors (analyzing draw
bounds, inserting clip planes, etc.).
* Bindless textures.
* Uber shaders.

Instead of having a fFontGlyphUsage on each device and one on each
document, just have the one on the document, and never merge.
Make fGlyphUsage accesible on SkPDFDocument.
Remove SkPDFGlyphSetMap::merge, ::reset, and SkPDFGlyphSet::merge.
SkPDFGlyphSetMap has an TArray of SkPDFGlyphSet, not TDArray of
SkPDFGlyphSet pointers. SkPDFGlyphSet and SkPDFBitset get move
constructors.
All tests produce exactly identical output PDFs.
