Doug Kwan 5f04b6bc3a Add ppc64le vector implementation of SHA-1. 
This change contains a C implementation of SHA-1 for POWER using
AltiVec. It is almost as fast as the scalar-only assembly implementation
for POWER/POWERPC family in OpenSSL but it is easier to maintain and it
allows error checking with tools like ASAN.

This is tested only for ppc64le. It may nor may not work for other
platforms in the POWER/POWERPC familiy.

Before:

SHA-1 @ 16 bytes: ~30 MB/s
SHA-1 @ 8K: ~140 MB/s

After:

SHA-1 @ 16 bytes: ~70 MB/s
SHA-1 @ 8K: ~480 MB/s
