functions with a single use; eliminating the single use may eliminate 
the function from the current module, but usually doesn't eliminate 
it from the final program.

Add R12 to the list of registers clobbered by 16-bit Thumb calls as a pre-caution. r12 could be live once we have mixed 32-bit and 16-bit instructions.

a new getSectionForMergableConstant hook.  This removes one dependence
of TAI on Type, and provides the hook with enough info to make the 
right decision based on whether the global has relocations etc.

Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it.

This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.
