PowerPC64 --plt-align

Alignment of plt stubs was broken, firstly because the option was
being dropped due to the alignment value not being set in the "params"
struct used in elf64-ppc.c, and secondly due to not calculating the
number of alignment boundary crossings correctly.

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.

Fix trampolines search code for conditional branches

For conditional branches that need more than one trampoline to reach its
target assembler couldn't always find suitable trampoline because
post-loop condition check was placed inside the loop, resulting in
premature loop termination. Move check outside the loop.

This fixes the following build errors seen when assembling huge files
produced by gcc:
    Error: jump target out of range; no usable trampoline found
    Error: operand 1 of 'j' has out of range value '307307'

Fix corrupted .eh_frame section with LTO and --gc-sections.

When --gc-sections is turned on during an LTO link, the .eh_frame sections
from deferred files are processed before those from the replacement files.
As a result, the section end-cap from crtendS.o is placed ahead of
the .eh_frame data from the replacement files. This patch fixes the bug
by skipping the layout of the deferred sections during GC pass 2.

[GOLD] PowerPC relaxation corner case

It's possible for the section grouping code to decide that the last
section looked at (the first section by address) doesn't fit into a
group.  In one case that section is already a group owner and that is

own group.  Like this:
