aa71428378 Initial TOC support for PowerPC64 object creation 
This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).

The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.

536a88ad5b When creating MCAsmBackend pass the CPU string as well. In X86AsmBackend 
store this and use it to not emit long nops when the CPU is geode which
doesnt support them.

Fixes PR11212.

it. It does need some some tests...

dc9a8a378d Reduce the exposure of Triple::OSType in the ELF object writer. This will 
avoid including ADT/Triple.h in many places when the target specific bits are
moved.

370b78d795 Move target-specific logic out of generic MCAssembler. 
Whether a fixup needs relaxation for the associated instruction is a
target-specific function, as the FIXME indicated. Create a hook for that
and use it.
