[driver] Improve the implementation of the -Ofast option. Specifically, allow the flags that fall under this umbrella (i.e., -O3, -ffast-math, and -fstrict-aliasing) to be overridden/disabled with the individual -O[0|1|2|s|z]/-fno- flags. This also fixes the handling of various floating point optimization flags that are modified by -ffast-math (and thus -Ofast as well). Part of rdar://13622687 llvm-svn: 180204
