Patch to implement SHA-512 instructions
Armv8.2 adds a number of new cryptography extensions, including SHA-512
instructions (FEAT_SHA512, which covers SHA512H, SHA512H2, SHA512SU0, and
SHA512SU1). I was trying to test some SHA-512 assembly with Valgrind and ran
into this.
I've attached a patch which implements them, mostly by adapting surrounding
code. I wasn't sure how adding tests worked, so it's missing those. Happy to
fill those in with some pointers.
