Add optimized slide_hash for POWER processors

This commit introduces a new slide_hash function that
uses VSX vector instructions to slide 8 hash elements at a time,
instead of just one as the standard code does.

Matheus Castanho [Mon, 25 May 2020 21:10:29 +0000 (18:10 -0300)] 
Preparation for POWER optimizations

Add the scaffolding for future optimizations for POWER processors. Now
the build is capable of correctly detecting multiple processor
sub-architectures (ppc, ppc64 and ppc64le) and also if features
needed for the optimizations are available during build and runtime.

With these changes, adding a new optimized function for POWER should be
as simple as adding a new file under arch/power/, appending build
instructions to the build files and editing functable.c accordingly.

The UNALIGNED_OK flag is now also added by default for powerpc64le
targets.
