03fce1c78c ld: Skip some x86 IFUNC tests for NaCl targets
Since NaCl linker may not support "-m elf_i386" nor "-m elf_x86_64", skip
x86 IFUNC tests for NaCl targets where "-m elf_i386" or "-m elf_x86_64"
are passed to linker.

233cc9c13a Don't generate PLT for IFUNC GOT/pointer reference
If a backend supports it, PLT entry isn't needed when all references
to a STT_GNU_IFUNC symbols are done via GOT or static function pointers.
For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for
preemptable symbols and R_*_IRELATIVE relocations for non-preemptable
symbols to update them with real function address.  For static pointer
pointers, we generate dynamic pointer relocations and store them in:

1. .rel[a].ifunc section in PIC object.
2. .rel[a].got section in dynamic executable.
3. .rel[a].iplt section in static executable.

We don't allocate GOT entry if it isn't used.

bae420ef26 Optimize x86 GOT32X/GOTPCRELX relocations
R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations
retrieve the symbol address via its GOT slot.  If the symbol address is
known at the link-time, we can use it directly by changing instruction
encoding.  Indirect branch can only be converted to PC relative direct
branch.  MOV can be changed to LEA or encoded differently with signed
address.  The subset of binary operations can be encoded only with
signed address.

If undefined weak symbol is resolved to zero link-time, we can use it
as address.  Zero addresss can't used with PC relative direct branch
when PIC is true since the current PC is unknown.  In 64-bit, 32-bit
relocation for PC relatiave direct branch to zero may also overflow.

If this optimization causes relocation overflow, --no-relax can be used
to work around it.

	PR ld/19609
	* elf32-i386.c (elf_i386_convert_load): Convert to R_386_32 for
	load with locally bound symbols if PIC is false or there is no
	base register.  Optimize branch to 0 if PIC is false.
	(elf_i386_relocate_section): Don't generate dynamic relocations
	against undefined weak symbols if PIC is false.
	* elf64-x86-64.c (elf_x86_64_convert_load): Disable optimization
	if we can't estimate relocation overflow with --no-relax.
	Convert to R_X86_64_32S/R_X86_64_32 for load with locally bound
	symbols if PIC is false.  Optimize branch to 0 if PIC is false.
