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.)

1. Make it work correctly with anonymous unions.
2. Don't compute it if the warning isn't enabled.
3. Optimize the algorithm slightly to make it linear time in the 
case where we don't produce any warnings.

Prefix IR dumps with LiveInterval indices when possible.  This turns
this:

	%ESI<def> = MOV32rr %EDI<kill>
	ADJCALLSTACKDOWN64 0, %RSP<imp-def>, %EFLAGS<imp-def,dead>, %RSP<imp-use>
	%reg1027<def> = MOVZX64rr32 %ESI
	%reg1027<def> = ADD64ri8 %reg1027, 15, %EFLAGS<imp-def,dead>
	%reg1027<def> = AND64ri8 %reg1027, -16, %EFLAGS<imp-def,dead>
	%RDI<def> = MOV64rr %RSP
	%RDI<def> = SUB64rr %RDI, %reg1027<kill>, %EFLAGS<imp-def,dead>
	%RSP<def> = MOV64rr %RDI

into this:

4	%reg1024<def> = MOV32rr %EDI<kill>
12	ADJCALLSTACKDOWN64 0, %RSP<imp-def>, %EFLAGS<imp-def,dead>, %RSP<imp-use>
20	%reg1025<def> = MOVZX64rr32 %reg1024
28	%reg1026<def> = MOV64rr %reg1025<kill>
36	%reg1026<def> = ADD64ri8 %reg1026, 15, %EFLAGS<imp-def,dead>
44	%reg1027<def> = MOV64rr %reg1026<kill>
52	%reg1027<def> = AND64ri8 %reg1027, -16, %EFLAGS<imp-def,dead>
60	%reg1028<def> = MOV64rr %RSP
68	%reg1029<def> = MOV64rr %reg1028<kill>
76	%reg1029<def> = SUB64rr %reg1029, %reg1027<kill>, %EFLAGS<imp-def,dead>
84	%RSP<def> = MOV64rr %reg1029

This helps greatly when debugging register allocation and coalescing
problems.

functions that return a value.  I was going to buffer the whole lot
up, but it should be easier to review if I check them in
incrementally.  Most of the forth coming changes either add a return
value, or make it impossible to return, or alter the return type.

and call PrintGlobalVariable, allowing elimination and simplification
of various targets.

Add PrefixPrinter arguments to the dump routines for MachineFunction and
MachineBasicBlock.  We'll use these shortly.

Add a small utility class to configure IR printers.  This will allow
printers to do neat and wonderful things when printing debug
information.  The ideas is to allow passes to configer printers to emit
pass-specific information when dumping IR.

Make a bunch of changes suggested by Chris and others to improve
efficiency.  Fix a few formatting bugs along the way.
