  [ExpandIRInsts] Support llvm.fpto{u,s}i.sat (#199174)

Previously, running ExpandIRInsts on a program which needs to expand a
vector fptoui.sat would hit llvm_unreachable, because the `scalarize`
function didn't handle this intrinsic.

This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.
