This patch removes the -f[no-]trapping-math flags from the -cc1 command line. These flags are ignored in the command line parser and their semantics is fully handled by -ffp-exception-mode. This patch does not remove -f[no-]trapping-math from the driver command line. The driver flags are being used and do affect compilation.
