Hi, All
Can gatekeeper help review this fix?
This bug is about unsupported intrinsic, more detailed info please refer to
https://bugs.open64.net/show_bug.cgi?id=602.
The failure is due to unsupported intrinsic for _mm_extract_pi16.
The fix is to add an entry for GSBI_IX86_BUILTIN_VEC_EXT_V4HI, and assign
the correspond operator according to the second arg.
Following is the fix:
