Subject: [PATCH] Fix compile errors for ARM targets when libyuv_use_neon =
 false

When building for ARM target with "libyuv_use_neon" set to false, the
build fails because there are still codes that reference to the NEON
related functions. To disable these code parts completely, the
LIBYUV_DISABLE_NEON macro should be defined when the "libyuv_use_neon"
is set to false.

Bug: libyuv:929
