PHI nodes can never reach the asmprinter, assert and die instead of printing

It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

how to fold notionally-out-of-bounds array getelementptr indices instead

Believe it or not, this is a simplification. :-)

Basically, this patch is working towards removing the hard-coded values that are
output for the CIE. In particular, the CIE augmentation and the CIE augmentation
size. Both of these should be calculated. In the process, I was able to make a
bunch of code simpler.

The encodings for the personality, LSDA, and FDE in the CIE are still not
correct. They should be generated either from target-specific callbacks (blech!)
or grokked from first-principles.

remove DebugLoc from MCInst and eliminate "Comment printing" from

target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

Make TypeBuilder's result depend on the LLVMContext it's passed.
TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.
