LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for

This cleans up the silly destroy methods and changes them to delete. It
also moves the TypeInfo and ValueInfo classes into the .y where we can

Make sure the IntegerValType has enough space for 2^23 bits.

Make sure that GEP indices are only 32 or 64 bits. We're not ready for
indices with other bit sizes yet.

For PR1093:
Implement upgrading of the varargs intrinsics. These must now have i8*
arguments. This patch bitcasts arguments to i8* and fixes the prototypes.
