gnu binutils: FSGSBASE assembly/disassembly

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Add some opcodes for assembling forthcoming VSX (Vector-Scalar eXtension)
support in the kernel. Userspace programs are expected to rely on LLVM's
integrated assembler or newer binutils.

Add support for the 'rdseed' instruction.

For GNU as, add two missing modes for each of the fcomip and fucomip
instructions. Partially obtained from OpenBSD by Pedro Giffuni, while I
added the fcomip variants.

Apparently this should help with compiling certain variants of WebKit.

binutils: add support for Intel SMAP-related instructions

Add support for stac/clac instructions to manipulate the flag
that controls the behaviour of Intel's Supervisor Mode Access
Prevention (SMAP) feature.

Fix cross-compilation of ia64 target code with clang.

Queisce warning about attempting to add char * together and use explicit
array indexing to indicate what is meant to be done

Add support for assembling and disassembling Intel Random Number
Generator extensions (e.g. the 'rdrand' mnemonic) to our copy of
binutils.

Add support for the 'invpcid' instruction to binutils and DDB's
disassembler on amd64.

reorder so all the flags are together and make the PCLMUL flag unique..

This fixes the problem on amd64 miscompiling mpboot.s causing boot
issues... We are still using gas for a few files in the kernel...

add support for AES and PCLMULQDQ instructions to binutils...

Thanks to Mike Belopuhov for the pointer to the OpenBSD patch, though
OpenBSD's gcc is very different that it only helped w/ where to modify,
not how... Thanks to jhb for some early reviews...

Add support for the 'invept' and 'invvpid' instructions. Beyond simply
adding appropriate table entries, the assembler had to be adjusted as
these are the first non-SSE instructions to use a 3-byte opcode (and a
mandatory prefix to boot).

Add support for the 'xsave', 'xrstor', 'xsaveopt', 'xgetbv', and 'xsetbv'
instructions. I reimplemented this from scratch based on the Intel
manuals and the existing support for handling the fxsave and fxrstor
instructions. This will let us use these instructions natively with GCC
rather than hardcoding the opcodes in hex.

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.

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.
