Merge commit 'cfe09ed28d8a65b671e8b7a716a933e98e810e32'

Conflicts:
	lib/Target/ARM/ARMFrameLowering.cpp
	lib/Target/Mips/MipsRegisterInfo.cpp
	lib/Target/X86/X86ISelLowering.cpp
	lib/Transforms/IPO/ExtractGV.cpp
	tools/Makefile
	tools/gold/gold-plugin.cpp

The only interesting conflict was X86ISelLowering.ccp, which
meant I had to essentially revert r167104. The problem is that we are
using ESP as the stack pointer in X86ISelLowering and RSP as the
stack pointer in X86FrameLowering, and that revision made them
both consistently use X86RegisterInfo to determine which to use.
