Add support for disassembling CET (including endbr64), XSS, OSPKE,
clflushopt, clwb, ptwrite, rdpid, serialize, WAITPKG, and vmfunc
extensions, as well as part of TSX. tpause and umonitor addr size
handling isn't 100% correct, but good enough to get the instruction
boundary.

Correct decoding of rex64 {fxsave,fxrstor,xsave,xrstor,xsaveopt}
to instead use a '64' suffix, ala "fxsave64".

Teach binutils how to assemble INVPCID and how to disassemble
INV{EPT,VPID,PCID}

Bring in FreeBSD changes to prevent clang triggering
-Wstring-plus-int -Wempty-body and -Wshift-negative-value warnings
as binutils is built with -Werror.

Recognise the rdseed instruction introduced with Broadwell.
Similar to changes made in FreeBSD.

Correctly consume mandatory 0x66 prefix when disassembling
aes{dec{,last},enc{,last},imc} instructions (regression in 2.17).

Correctly disassemble aeskeygenassist.

A first attempt at merging our local changes and fixes into the 2.17 codebase.
ld(1) needs a lot more work, as the upstream code evolved significantly since
2.15, mostly due to changes in PIE binaries layout, and we had already
diverged significantly to implement W^X.
