Fix incorrect _mm_cvtsbh_ss.
After supporting real __bf16, the implementation of _mm_cvtsbh_ss went
wrong.
The patch add a builtin to generate pslld for the intrinsic, also
extendbfsf2 is supported with pslld when !HONOR_NANS (BFmode).
truncsfbf2 is supported with vcvtneps2bf16 when
!HONOR_NANS (BFmode) && flag_unsafe_math_optimizations.
