Subject: [PATCH] Optimize AES-GCM for uarchs with unroll and new instructions

Increase the block numbers to 8 for every iteration.  Increase the hash
table capacity.  Make use of EOR3 instruction to improve the performance.

This can improve performance 25-40% on out-of-order microarchitectures
with a large number of fast execution units, such as Neoverse V1.  We also
see 20-30% performance improvements on other architectures such as the M1.

Assembly code reviewd by Tom Cosgrove (ARM).
