Reason for revert:
GYP's failing on most (all?) bots.

Aarch64 support
This change contains the necessary modifications to have Skia build and
run properly on an ARMv8 processor in aarch64 execution state.
Here's a list of the changes:
- add an arm64 target to the build system + SK_CPU_ARM64 flag
- MatrixTest was failing when built in Release mode. Fused MAC
instructions were generated which made some intermediate results
more accurate. As the test relies on result comparison, the more
precise results when compared to others led to a gap bigger than
what was tolerated. As I don't know if some actual skia code relies
on results being comparable, I've disabled fused MAC instruction
with -ffp-contract=off for arm64.
- Modify include/core/SkOnce.h to have barriers work.
- SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS.
- use existing Xfermode optimisations with modifications that can be
removed in the future when toolchains are ready. Also save a few
instructions is two Xfermodes (will apply to ARM too).
- use existing SkBoxBlur and SkMorphology optimisations.
- use existing SkBlitMask optimisations
- use existing BitmapProcState and Convolution optimisations.
Future changes will include:
- Blitters (only partialy merged upstream)
- SkUtils (there's little value in sending asm optimisations without
having them benchmarked on real hardware).

Valgrind's whining about m.setConcat(m, I). That special cases into m =
m, which compiles into memcpy(&m, &m, sizeof(m)), and then Valgrind
decides that's not kosher because &m and &m overlap. (memmove would
have been fine, but this is compiler generated code; not much we can do.)
preConcat gets us the same thing with an early can-we-noop check for I,
sidestepping the whole problem.

Use path rendering to render the text from outlines if supported by the
GPU. Implement this in GrStencilAndCoverTextContext by copying large
chunks of code from GrBitmapTextContext (drawText) and
GrDistanceFieldTextContext (drawPosText).
The drawing is implemented with "instanced" path drawing
functions.
Moves the creation of the "main" text context from SkGpuDevice to the
GrContext::createTextContext. This is done because the decision of which
text renderer is optimal can be made only with the internal
implementation-specific information of the context.

This will be used in Blink to accommodate matrices that contain
rotation or shearing. This is a generalization of SkResizeImageFilter,
so I've replaced all uses of SkResizeImageFilter in Skia. (It might be
easier to review by diffing it with SkResizeImageFilter, too.)

Add interface to draw multiple paths in a single "command" to a draw
target. Implement this interface in GrGpuGL with NVPR "instanced"
calls.
The instanced calls accept list of paths and list of transformations as
their parameters. The transformations are at this moment expected to be
2d affine transformations, as the functions are called only for text
rendering.
This will be used when drawing fonts. Later it can be maybe be used in
GrInOrderDrawBuffer to aggregate many draw calls into one instanced draw
call, similar to drawing rects.

This was crashing on the GPU path, due to a failed texture allocation.
The belt-and-suspenders fix is to:
1) Limit the GPU path to only allocate up to maxTextureSize.
2) Limit both the raster and GPU paths to reasonable blur sizes (box blur
kernel size of 1000, resulting in a sigma limit of 532).

When gathering information about a picture (in the new SkDevice::EXPERIMENTAL_optimize entry point) it is necessary to be able to correlate the gathered information with the command in the SkPicture (so the information can later be combined with the similarly indexed information from the BBH). This entry point exposes that information to friend classes.
