A better-scheduled PPC SHA-1 implementation.

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.

No copyright is claimed on the changes to Paul Mackerras' work below.
