GCM GHASH function (NIST SP800-38D)

Architecture: arm using - PMULL (Polynomial Multiply Long) instructions - NEON (Advanced SIMD) extensions - ARMv8 Crypto Extensions

Use an implementation of GHASH (used by the GCM AEAD chaining mode) that uses the 64x64 to 128 bit polynomial multiplication (vmull.p64) that is part of the ARMv8 Crypto Extensions, or a slower variant that uses the vmull.p8 instruction that is part of the basic NEON ISA.
