[X86] Add custom lowering for v2i64->v2f32 strict_sint_to_fp/strict_uint_to_fp... 

[X86] Add custom lowering for v2i64->v2f32 strict_sint_to_fp/strict_uint_to_fp for avx512dq+avx512vl targets.

With avx512dq+avx512vl we have instruction that implements this and
places zeroes in the upper 64-bits of the destination xmm register.
