H.J. Lu 3d5a60de52 x86-64: Add R_X86_64_CODE_4_GOTPCRELX 
For

	mov        name@GOTPCREL(%rip), %reg
	test       %reg, name@GOTPCREL(%rip)
	binop      name@GOTPCREL(%rip), %reg

where binop is one of adc, add, add, cmp, or, sbb, sub, xor instructions,
add

 # define R_X86_64_CODE_4_GOTPCRELX  43

if the instruction starts at 4 bytes before the relocation offset.  It
similar to R_X86_64_GOTPCRELX.  Linker can treat R_X86_64_CODE_4_GOTPCRELX
as R_X86_64_GOTPCREL or convert the above instructions to

	lea	name(%rip), %reg
	mov	$name, %reg
	test	$name, %reg
	binop	$name, %reg

if the instruction is encoded with the REX2 prefix when possible.
