475c55393a 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).

72f42bbc9b For PR786: 
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

these changes. This was done to speed up link times.
