Updates GrDrawContext to crop filled rects to the clip bounds before
creating batches for them. Also adds clipping logic to ignore scissor
when the draw falls completely inside. These two changes combined
reduce API traffic and improve batching.
In the future this can and should be improved by switching to floating
point clip boundaries, thus allowing us to throw out non pixel aligned
rectangle clips as well.

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.

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.

- Sk4f would be my choice, but it's not allowed in include/
- SkColor4f and SkPM4f are specified to be unpremultiplied/premultiplied, whereas GrColor (and GrColor4f) are either, depending on context.
This adds 12 bytes to GrPaint. Not sure if we want to pay that price. The precision loss for a single value (vs. in a gradient, etc...) may not justify changing the storage type here. Easy enough to back that part out, while still keeping the 4f intermediate type for the helper math that it adds, and for storage and parameter passing in other locations.

Ensures that ".get()" always returns null when a container is empty.
Also ensures consistent assert behavior for array counts.
There are still differences in that the malloc variants take a size_t
and the arrays take an int, and that SkAutoSTMalloc defaults to the
stack-allocated buffer wheras the other containers default to null.
