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.

Add some support for iterative coalescers to calculate a joined live
range's weight properly.  This is turned off right now in the sense that
you'll get an assert if you get into a situation that can only be caused
by an iterative coalescer.  All other code paths operate exactly as
before so there is no functional change with this patch.  The asserts
should be disabled if/when an iterative coalescer gets added to trunk.
