  1. [X86] Use zero vector to extend to 512-bits for strict_fp_to_uint (details)
Commit c5b4a2386b51a18daad7e42040c685c2e9708c47 by craig.topper
[X86] Use zero vector to extend to 512-bits for strict_fp_to_uint
v2i1->v2f64 on targets with AVX512F, but not AVX512VL.
In the worst case, this requires a 128-bit move instruction to
implicitly zero the upper bits. In the common case, we should recognize
the producing instruction already zeroed the upper bits.
