[PATCH] D62731: Add support for options -frounding-math, ftrapping-math, -fp-model=, and -fp-exception-behavior=, : Specify floating point behavior

mibintc added a comment.

Respond to recent code review from @rjmccall ; I modified the test cases and added functions for translating between the LangOptions enumeration and llvm enumeration for rounding-mode and exception-behavior.  I wasn't able to use BooleanFFlag because at the moment that is only usable for unsupported options.
