patch to add aes and pclmulqdq instructions to gcc

[John-Mark Gurney]

Mike Belopuhov pointed me to the patch in OpenBSD:
http://freshbsd.org/commit/openbsd/0babc91a00b1f1953637bb39c8ec97aef704629e/diff.txt

While OpenBSD's binutils is quite different than FreeBSD's, I was able
to use his patch to teach binutils how to assemble and disassemble the
aes and pclmulqdq instructions.

I have done basic tests, such as verified that it can assemble the aesni
module and get the same results, and assemble a sample file for
pclmulqdq..  For each of these tests, I have verified that it's output
matches (as close as possible, as gcc/clang compile callq's differently)
clang on amd64..

I have attached the patch, and it is also availble at:
http://people.freebsd.org/~jmg/gcc.aes.patch

Comments?

I have not passed it through a make universe yet, but will before
committing...

I am also working on basic intrinsics header files for these instructions
too...
