AMD64 Bit Matrix Multiply and Bit Reversal Instructions (docs.amd.com)

I believe this means "VBMACXOR16X16X16" is now officially the longest x86 mnemonic

I love me some isa extension, I'd love to know what these are intended and useful for for though. 1 bit inference? I hear they could be useful in crypto as well, but that's out of my field.
