[Flang] Add -ffast-real-mod back for further control of MOD optimizations (#167118) It turns out that having `-ffast-math` as the only option to control optimizations for MOD for REAL kinds (PR #160660) is too coarse-grained for some applications. Thus, this PR adds back `-ffast-real-mod` to have more control over the optimization. The `-ffast-math` flag will still enable the optimization, and `-fno-fast-real-mod` allows one to disable it.
