gas: Implement the .inst assembler directive for arm.

We normally use the binutils from ports but on other systems this
is required for building gcc 4.9.

gas/config/tc-arm.c: Minor re-sorting to match upstream history.

No functional change.

Fix mrc and mrc2 with APSR_nzcv. Binutils encodes it internally as 0 where
we need it to be set to 15 for it to be equivalent to r15.

Allow the UAL APSR_nzcv format for the mrc and mrc2 instructions. The clang
integrated assembler only allows these forms so binutils will need to
support them.

Avoid undefined behaviour in gas's rotate_left() macro for n == 0.
Otherwise, clang can effectively remove the first iteration of the for
loops where this macro is invoked, and as a result, "cmp r0, #99" fails
to assemble.

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'.

Merge from projects/arm_eabi_vfp r255380:

Fix the VCVT instruction. It must round towards zero when converting from
a floating-point to an integer value. This was not the case causing issues
when printing certain values.

There is a VCVTR instruction that will round depending on the current
rounding mode. We don't yet support this instruction, or setting the
rounding mode.

Silence a warning that is incorrect on ARMv6 and later. In the smull, umull,
smlal, and umlal the output registers are allowed to be the same as either
input registers, where in ARMv4 and ARMv5 they could only be the same as the
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++
exceptions on ARM EABI with static binaries.

Recognise vfpv2 as a value for the ARM .fpu asm directive. Clang generates
these even when building soft floating-point code

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.

Make GNU as recognize the ARM 'rrx' mnemonic, which can be generated by
clang for certain expressions. Code taken from Apple cctools (GPLv2).

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.
