  Log Message:
  -----------
  [IVDescriptors] Remove function FMF attribute check for FP min/max reduction (#183523)

Remove the use of function attributes no-nans-fp-math and
no-signed-zeros-fp-math in FP min/max reduction detection. The required
fast-math flags nnan and nsz should be present on the intrinsic calls,
fcmp and select instructions themselves.
