Added X86FunctionInfo subclass of MachineFunction to record whether the
...
function that is being lowered is forced to use FP. Currently this is only
true for main() / Cygwin.

Now that PR633 is implemented, the CBE can know to emit _setjmp/_longjmp
...
when available. This speeds up hexxagon from 18.61s to 16.61s with the CBE on
PPC Mac OS (for reference, LLC is 15.48s and GCC is 23.35s).
