0a3a6f2ceb Remove the XCore custom implementation of MergeableConstSection, relying on 
the generic ELF version instead.  This will result in its mergable constant
sections getting named ".rodata.cst4" instead of ".cp.const4", but the
linker looks at the section flags, not the name of the section AFAICT.

implemented exactly the same way as its ELFTargetAsmInfo subclass 
has them.

45160af6bd 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.)

94bfedaf40 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.

ac0f5e081e whitespace cleanups, make the MipsAsmPrinter::doInitialization 
chain to the super class instead of initializing mangler directly.
This gives it .file and module level inline asm support among other
things.

433fbf959a fix Sparc, SystemZ, and MSP430 to not override AsmPrinter::doInitialization. 
This eliminates redundancy setting up the mangler and adds support to them
for module-level inline asm and a .file directive.

c142755cec Another rewriter bug exposed by recent coalescer changes. ReuseInfo::GetRegForReload() should make sure the "switched" register is in the desired register class. I'm surprised this hasn't caused more failures in the past.
