  Log Message:
  -----------
  [DAGCombine] Remove the check for unsafe-fp-math when we are checking the AFN

We are checking the unsafe-fp-math for sqrt but not for fpow, which behaves inconsistent.
As the direction is to remove this global option, we need to remove the unsafe-fp-math
check for sqrt and update the test with afn fast-math flags.
