6dae757a07 Don't give a massive inlining cost bonus to available_externally
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.

298414ec18 remove the SelectSectionForMachineConst hook, replacing it with
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.

fc6ad402fb 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.

80607c9b2b 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.

add the appropriate parameterization to TargetAsmInfo in the future to support
this.

b3e7171926 Remove shift amount flavor. It isn't actually complete enough to
be useful, and it's currently unused.  (Some issues: it isn't actually 
rich enough to capture the semantics on many architectures, and
semantics can vary depending on the type being shifted.)

	%RDI<def> = SUB64rr %RDI, %reg1027<kill>, %EFLAGS<imp-def,dead>

into this:

12	ADJCALLSTACKDOWN64 0, %RSP<imp-def>, %EFLAGS<imp-def,dead>, %RSP<imp-use>

28	%reg1026<def> = MOV64rr %reg1025<kill>
36	%reg1026<def> = ADD64ri8 %reg1026, 15, %EFLAGS<imp-def,dead>
