OLD: movl L___stack_chk_guard$non_lazy_ptr, %eax
where 'new' is coming out of the MCInst version of the printer.

what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.
I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)

instead?)
ARM v7 supports unaligned access for i16 and i32, some v6 variants support it
as well.

PIC16DebugInfo currently rely on NameStr of composite type descriptors to uniquely
identify debug info for two aggregate type decls with same name.
This implementation will change when we have MDNodes based debug info implemenatation in place

This hopefully finishes unbreaking the previous behavior that I broke before.

libcall. Take advantage of this in the ARM backend to rectify broken
choice of CC when hard float is in effect. PIC16 may want to see if
it could be of use in MakePIC16Libcall, which works unchanged.

- This makes it possible to do some correctness checking of the parsing and
matching, since we can compare the results of 'as' on the original input, to
those of 'as' on the output from llvm-mc.
- In theory, we could now have an easy ATT -> Intel syntax converter. :)
