dd7e64d45b Optimize out i386/x86-64 JUMP_SLOT relocation 
When there are both PLT and GOT references to the same function symbol,
linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT
reference.  A run-time JUMP_SLOT relocation is created to update the
GOTPLT slot and a run-time GLOB_DAT relocation is created to update the
GOT slot.  Both JUMP_SLOT and GLOB_DAT relocations will apply the same
symbol value to GOTPLT and GOT slots, respectively, at run-time.

This optimization combines GOTPLT and GOT slots into a single GOT slot
and removes the run-time JUMP_SLOT relocation.  It replaces the regular
PLT entry:

	indirect jump	[GOTPLT slot]
	push		relocation index
	jump		PLT0

with an GOT PLT entry with an indirect jump via the GOT slot:

	indirect jump	[GOT slot]
	nop

and resolves PLT reference to the GOT PLT entry.

We must avoid this optimization if pointer equality is needed since
we don't clear symbol value in this case and the dynamic linker won't
update the GOT slot.  Otherwise, the resulting binary will get into an
infinite loop at run-time.
