  -----------
  [SelectionDAG] Remove `UnsafeFPMath` in LegalizeDAG (#146316)

These global flags hinder further improvements like [[RFC] Honor pragmas
with
-ffp-contract=fast](https://discourse.llvm.org/t/rfc-honor-pragmas-with-ffp-contract-fast)
and pass concurrency support. Remove them incrementally.
