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.

Tested by: dim
Obtained from: OpenBSD

MFC r247012 (by jmg):

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...

MFC r247117 (by jmg):

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...

MFC r255192 (by jhb):

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

MFC r256112:

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

MFC 238123,238167:
- 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.
- 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).

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.
