binutils: fix gas that doesn't handle MIPS1 FPR load hazard correctly.

Fixes PR/57680.
Should be pulled up to netbsd-10, netbsd-9, and netbsd-8.

binutils/gas: mips: Dedup merge botch

This code segment got duplicated during binutils 2.26 merge.

merge conflicts, regen for x86.

Fix a bug where the octeon+ saa/saad instructions think they are using the AT
register when they actually aren't.

Fix bad cut'n'paste in previous commit.
This should fix the remaining loogson build issues.

update for new binutils code our local patch to avoid warnings when macro are
used for loongson2f workarounds. Should fix mips64el kernel builds.

Fix trap_zero_jump for new binutils.

XXX someone who really understand this should check it.

resolve conflicts

branches: 1.10.2; 1.10.8;
put -mfixloongson2f-btb back in the command line options list

add OPTION_FIX_LOONGSON2F_BTB and OPTION_NO_FIX_LOONGSON2F_BTB
options back to the enum.

Merge new binutils. Only x86_64 works now; the rest will need to run mknative
again (at least).

Hide instructions added by -mfix-loongson2f-jump in the same way as
-mfix-loongson2f-btb, to avoid a gas warning "macro expanded into
multiple instructions" (which cause GDIUM kernel build failure
as it's built with -Wa,-mfix-loongson2f-jump -Wa,--fatal-warnings).

Add a fix-loongson2f-btb option to gas, from OpenBSD.
This works around a bug in the branch prediction logic of the
CPU which can cause a hard hang. The existing fix-loongson2f-jump
works around the same bug, but by 'fixing' the jump target to be within the
same 256MB region as the kernel. This will (silently) cause a jump
to the wrong address if the jump is intentionally to some other
region (e.g. a call to pmon).
fix-loongson2f-btb instead works around the issue by adding an explicit flush
of the branch target buffer (via a write to a cop0 register) before every
jump register instruction.

Add a -mtrap-zero-jump option for mips that causes a trap instruction to
fire before a jump to a zero or "near" zero address. This can't be used
with MIPS1 kernels since MIPS1 doesn't have a trap instruction (it will
be silently ignored).

Pull in change to support -m[no-]fix-loongson2f-{nop,jump}

Pull in MIPS XLR (XLS) support from patch in
http://sourceware.org/ml/binutils/2009-01/msg00383.html
This replaces local changes to support some xlr instructions.

Pull in fixes from upstream revision 1.406 to avoid string formatting
warnings. Fixes build with newer GCC, like the one in Snow Leopard.
