59375bae75 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 :-)

68f316a93c 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.

This helps hiding the LiveRange class which really should be private.

a0a5015a35 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.

This fixes PR8357.

8fae045502 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).

ecf3e62010 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.

c9709f154d Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

2b428a0ab8 fix the expansion of va_arg instruction on PPC to know the arg 
alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.
