2011-11-14rs6000: Rewrite sync patterns for atomic; expand early.Richard Henderson5-864/+582
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. From-SVN: r181370
