This is about 15% faster that the current sha1ppc.S on a G4, and
5% faster on a G5 when hashing 10 million bytes, unaligned.
(The G5 ratio seems to get better as the sizes fall.)
It's also somewhat smaller, due to using load-multiple instructions.

Here is a SHA1 implementation with the core written in PPC assembly.
On my 2GHz G5, it does 218MB/s, compared to 135MB/s for the openssl
version or 45MB/s for the mozilla version.
