  Log Message:
  -----------
  ConstantFolding: Constant fold denormal inputs to canonicalize for IEEE

This makes it possible to use canonicalize to perform a dynamic check
for whether denormal flushing is enabled, which will fold out when the
denormal mode is known. Previously it would only fold if denormal
flushing were known enabled.
