MFC r264238:

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.

MFC r261175:

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.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

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.

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.

Obtained from: projects/binutils-2.17

Merge ^/vendor/binutils/dist@214571 into contrib/binutils, which brings
us up to version 2.17.50.20070703, at the last GPLv2 commit.

Amongst others, this added upstream support for some FreeBSD-specific
things that we previously had to manually hack in, such as the OSABI
label support, and so on.

There are also quite a number of new files, some for cpu's (e.g. SPU)
that we may or may not be interested in, but those can be cleaned up
later on, if needed.

Import the binutils master branch from the sourceware CVS repository,
exactly as it was on Tue, 3 Jul 2007 07:54:19 +0000.

Corresponds to git commit 397a64b350470350c8e0adb2af84439ea0f89272,
which was the last commit before switching to GPLv3.
