  Revert "[flang] Respect math flags during conversions (#214311)" (#225887)

This reverts commit 688119653fd40fa46244e1c300e728677a4f001a.

This caused a regression in Fujitsu test 0291/0291_0008.f with
`-ffast-math -march=native -03`. That test does a conversion that always
overflows, so without saturating math it produces poison, which causes
it to treat the rest of the routine as unreachable, resulting in a crash
on x86. I'll have to try another approach.
