in r396, NV12ToRGB565 is optimized using 2 steps:
NV12ToARGB_Neon
ARGBToRGB565_C

Which adds it to the list of failing unittests for Neon.
[==========] 230 tests from 1 test case ran. (107427 ms total)
[  PASSED  ] 222 tests.
[  FAILED  ] 8 tests, listed below:
[  FAILED  ] libyuvTest.I420ToRGB565_OptVsC
[  FAILED  ] libyuvTest.I420ToRGB565Invert_OptVsC
[  FAILED  ] libyuvTest.I420ToARGB1555_OptVsC
[  FAILED  ] libyuvTest.I420ToARGB1555Invert_OptVsC
[  FAILED  ] libyuvTest.I420ToARGB4444_OptVsC
[  FAILED  ] libyuvTest.I420ToARGB4444Invert_OptVsC
[  FAILED  ] libyuvTest.NV12ToRGB565_OptVsC
[  FAILED  ] libyuvTest.NV12ToRGB565Invert_OptVsC

But the one step conversions pass.
[       OK ] libyuvTest.I420ToRGB24_OptVsC (3177 ms)

The reason for failure is:
1. the unittest compares bytes, which isnt valid for 555/565/4444.
2. The NEON I420ToARGB doesnt exactly match the C version.

Recommend making Neon math exactly match C if possible.
