gas: mark dwarf2_loc_mark_labels as extern

Compiling with -fno-common complains as this header's included in multiple
compilation units. In fact, the proper definition of dwarf2_loc_mark_labels
already exists in dwarf2dbg.c, so simply mark this declaration with extern.

MFC r312899: add octeon+ as an alias for octeon in GCC & binutils

r208737 added support for the "mips64r2" architecture and "octeon" CPU,
and the saa/saad instructions.

Upstream binutils also added the "octeon+" CPU, and the saa/saad
instructions are only available in octeon+, not octeon. Since our
base system tool chain already accepts saa/saad with -march=octeon,
just allow octeon+ as an alias.

This allows the use of octeon+ in kernel config files, for use with both
external tool chain and in-tree GCC/binutils.

Also includes GCC FBSD_CC_VER bump (r313041 in HEAD)

Rename elf*-powerpc into elf*-powerpc-freebsd in binutils

The powerpc support was the only supported architecture not prepending the elf format name
with "-freebsd" in base this change makes it consistent with other architectures.
On newer version of binutils the powerpc format is also prepended with "-freebsd".

Also modify the kernel ldscripts in that regards.

As a result it is now possible cross build the kernel on powerpc using newer binutils

Add movw and movt relocations to the list of relocations against function
names that must nnot be adjusted. This fixes a bug where code such as:
movw r2, :lower16:symbol
movt r2, :upper16:symbol

It is common for clang to generate such code when targeting armv7.

Allow vld and vst instructions to use the canonical form from ARM ARM when
including an alignment. Previously binutils would only allow instructions
in the form "vld1.64 {d0, d1}, [r0, :128]" where the final comma should
not be there, instead the above instruction should be
"vld1.64 {d0, d1}, [r0:128]".

This change duplicates the alignment code from within the function to
handle this case.

Add all the dmb/dsb optional limitations, including the alternative values.
These are needed for some code llvm generates when targeting ARMv7.

Allow the optional limitation on dmb instructions as is already the case
with dsb instructions.

Teach as(1) to handle the arm .arch_extension pseudo-op, which accepts
the same values as the -march= command line option. Add support for the
"sec" extension (security extensions).

We've been getting away without support for the sec extension because
it's bogusly enabled even on arches where its presence is optional. This
support for .arch_extension is being added mainly so that we can use the
right directives in our source code, and that helps folks using external
toolchains (and will help us when we finally update our toolchain).

Fix an bug in as(1) parsing of arm -march=arch+ext options. Compare the
arch name to just the characters before the '+' in 'arch+ext'.

Make gas accept any PowerPC instruction by default. This is a local change,
and will not be submitted upstream.

Silence a warning that is incorrect on ARMv6 and later. In the smull, umull,

last input register.

do_vfp_vmrs and do_vfp_vmsr should not return anything.

Add support for the vmsr and vmrs instructions. This supports the system
level version of the instructions. When used in userland the hardware only
allows us to read/write FPSCR.

Some ARM vmov similar to 'vmov.f32 s1, s2' will incorrectly have the second
register added to the symbol table by the assembler. On further
investigation it was found the problem was with the my_get_expression
function. This is called by parse_big_immediate.

Fix this by moving the call to parse_big_immediate to the end of the if,
else if, ..., else block.

Clear the memory allocated to build the unwind tables. This fixes C++

Merging of projects/armv6, part 3

r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.

o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default
ABI to one of o32, n32 or n64. If it is not set, o32 is assumed as that is
the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is
necessary to have a working "cc" if e.g. mips64 is specified, as binutils
will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
--end-group. This is required for static linking to work on n64 with the
interdependencies between libraries there. This is what other OSes that
support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
former being what libgcc, etc., check and the latter seemingly being a
misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit
ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
the MIPS32 ISA, when we are supporting or will support some systems based on
earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
and add flags and code necessary to support Octeon-specific instructions.
This should also make merging opcodes for other modern architectures easier.
