This is needed in order to be able to commit when
working from a pure Git checkout, since the Git updater
is configured to sync using a http-URL
(in services/cron/git_updater/project_config.py)

Being able to use a pure Git checkout is a natural step
towards switching over libyuv to Git.

scale to 3/4 or 3/8 with odd width destinations efficiently.  previously if width was not multiple of what the simd loop would do (24), scaling would fall back on slower C code.  This change allows SIMD to be used for most of the scaling and C for the remainder, improving efficiency.

Enable assembly for clangcl build on Windows.  Previously assembly was disabled so clangcl would work, but only with C code.  As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both.  In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel.
