  Log Message:
  -----------
  [FPEnv][AtomicExpand] Correct strictfp attribute handling in AtomicExpandPass (#87082)

The AtomicExpand pass was lowering function calls with the strictfp
attribute to sequences that included function calls incorrectly lacking
the attribute. This patch corrects that.

The pass now also emits the correct constrained fp call instead of
normal FP instructions when in a function with the strictfp attribute.

Test changes verified with D146845.
