* Update gflags to newer repository location (plain copy
  from the files in WebRTC).
* Add workarounds for mojo dependency (see
  http://bugs.webrtc.org/5629 for more details).
* Update libyuv_unittest to generate user friendly
  run-scripts for Android in out/{Debug,Release}/bin
* Fix Android test execution by adding explicit dependency
  on Chromium's base/base.gyp:base_build_config_gen

This roll also solves the compile problem for Mac ASan bots.

Inline that uses temporary variables is currently initializing them
to 0 and passing in as output "+r".
This CL replaces the output constraint to "=&r" for most meaning an
output with early write (before inputs).  This allows the initialize
to zero step to be removed, saving 1 instruction.

They are not needed, and due to them there was a call to _xgetbv()
without a declaration of the function.  This used to work because we
implicitly included intrin.h in all translation units with clang-cl, but
we want to stop doing that.

NV12ToRGB565Row_AVX2 with call to NV12ToARGBRow_AVX2 and
ARGBToRGB565Row_SSE2.
