Temporarily Revert "Add support for options -frounding-math, ftrapping-math, -ffp-model=, and -ffp-exception-behavior="

and a follow-up NFC rearrangement as it's causing a crash on valid. Testcase is on the original review thread.

This reverts commits af57dbf12e54f3a8ff48534bf1078f4de104c1cd and e6584b2b7b2de06f1e59aac41971760cac1e1b79
