all: VAES instructions (#358)
Adds "Vector Advanced Encryption Standard" instruction set. These are added via the `opcodesextra` mechanism #345, since they're missing from the opcodes database. Contributed by @vsivsi. Extracted from #349 with minor tweaks. Co-authored-by: Vaughn Iverson <vsivsi@yahoo.com>
