Add R_X86_64_[REX_]GOTPCRELX support to gas and ld This patch adds support for the R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 to gas and ld.

Add "-z call-nop=PADDING" option to ld The ld linker can transform indirect call to a locally defined function, foo, via its GOT slot, to either "NOP call foo" or "call foo NOP" where NOP is a 1-byte NOP padding.
