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).

Generate SkUserConfig.
Include arm64 as another build flavor.
Add tests.
gyp/common_conditions.gypi:
Add conditions for Android framework. These will get written into the generated SkUserConfig.
include/core/SkUserConfig.h:
Generated version that will ultimately be checked into Android (but not here).
platform_tools/android/bin/gyp_to_android.py:
Generate SkUserConfig.
Add arm64 (note that arm64 is not currently respected by our gyp files, so it results in use _none.cpp for the various opts).
Reset the common defines, which are now passed to the generated SkUserConfig.
platform_tools/android/gyp_gen/generate_user_config.py:
New script to generate SkUserConfig.h.
platform_tools/android/gyp_gen/gypd_parser.py:
Fix a lint error (unused import).
platform_tools/android/gyp_gen/makefile_writer.py:
Append any remaining DEFINES to LOCAL_CFLAGS (previously this was done during parsing).
Add a warning for arm64 (corresponds to downstream Android.mk).
platform_tools/android/gyp_gen/vars_dict_lib.py:
Add OrderedSet.reset().
Add DEFINES to VarsDict.
platform_tools/android/tests/expectations/:
Add and update expectations files.
platform_tools/android/tests/generate_user_config_tests.py:
New test for generate_user_config.py
platform_tools/android/tests/inputs/SkUserConfig.h:
Input to the new test, so we don't have to update the expectations each time the real SkUserConfig.h changes.
platform_tools/android/tests/makefile_writer_tests.py:
Add a way to rebaseline test_write_local_vars, which has changed.
Refactor EXPECTATIONS_DIR and compare_files into a separate file for sharing with generate_user_config_tests.py.
platform_tools/android/tests/utils.py:
Common code for tests.
platform_tools/android/tests/var_dict_tests.py:
Use a for loop to test the new key (DEFINES) and future proof this test to test any new keys in the future.

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.
