Tomas Vondra c60e520f6e Use memcpy instead of a byte loop in pglz_decompress 
The byte loop used in pglz_decompress() because of possible overlap may
be quite inefficient, so this commit replaces it with memcpy. The gains
do depend on the data (compressibility) and hardware, but seem to be
quite significant.
