rs6000: Rewrite sync patterns for atomic; expand early.

The conversion of the __sync post-reload splitters was half
complete.  Since there are nearly no restrictions on what may
appear between LL and SC, expand all the patterns immediatly.
This allows significantly easier code generation for subword
atomic operations.
