c82bc561b5 crc32-vpmsum: Restore non volatile registers on zero length CRC 
This is never hit in practice, because the wrapper code catches it,
but fix the zero length exit to restore all the non volatile registers.

a2c826b6aa MDEV-9872: New Power8 crc32(ieee) optimized functions 
These are different from the existing crc32 functions which
where really crc32c.

9c2215e022 MDEV-9872 - Add common optimized CRC32 function interface 
Move crc32-vpmsum to extra.
Compile static crc32-vpmsum instead of adding sources directly.
Make use of crc32-vpmsum via my_checksum().

Based on contribution by Daniel Black.
