Zvkb - Vector Cryptography Bit-manipulation

Vector bit-manipulation instructions that are essential for implementing common cryptographic workloads securely & efficiently.

Note	This Zvkb extension is a proper subset of the Zvbb extension. Zvkb allows for vector crypto implementations without incuring the the cost of implementing the additional bitmanip instructions in the Zvbb extension: vbrev.v, vclz.v, vctz.v, vcpop.v, and vwsll.[vv,vx,vi].

Mnemonic	Instruction
vandn.[vv,vx]	[insns-vandn]
vbrev8.v	[insns-vbrev8]
vrev8.v	[insns-vrev8]
vrol.[vv,vx]	[insns-vrol]
vror.[vv,vx,vi]	[insns-vror]
