[X86] Add custom promotion of narrow fp_to_uint/fp_to_sint operations under -x86-experimental-vector-widening-legalization.
This tries to force the result type to vXi32 followed by a truncate. This can help avoid scalarization that would otherwise occur.
There's some annoying examples of an avx512 truncate instruction followed by a packus where we should really be able to just use one truncate. But overall this is still a net improvement.
