Makes it possible to use options with names like "Wa,".
Also fixes the -Wall option handling as a side-effect.

Move the various analyses used by GVN into static variables so we don't have to keep passing them around or refetching them.

SCCP like sparse lattice analysis with relative ease.  Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)

include backslashes on Windows. This should fix llvm-ld problems on win32.

side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

llvm-gcc does not currently use VAArgInst; it lowers va_arg in the
front-end.

If all sources of a PHI node are defined by an implicit_def, just emit an implicit_def instead of a copy.
