register operand.

17b443df43 Second set of ARM/MC/ELF changes. 
Added ARM specific ELF section types.
Added AttributesSection to ARMElfTargetObject
First step in unifying .cpu assembly tag with ELF/.o
llc now asserts on actual ELF emission on -filetype=obj :-)

d3d2ddc78e Clang's #include handling apparently doesn't work for libstdc++'s 
fenv.h. See PR6907 for details. Work around this in FEnv.h to fix
the seflhost build.

4f9af2ef65 PowerPC varargs functions store live-in registers on the stack. Make sure we use 
virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

01855071e2 When figuring out which operands match which encoding fields in an instruction, 
try to match them by name first. If there is no by-name match, fall back to
assuming they are in order (this was the previous behavior).

40ef4fe82a Properly handle reloading and spilling around partial redefines in 
LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.
