rs6000: fix misleading new patterns of splitters
As a comment in https://gcc.gnu.org/pipermail/gcc-patches/2022-August/599556.html Those splitters call rs6000_emit_set_const directly, and the replacements are never used. Using (pc) would be less misleading. gcc/ChangeLog: * config/rs6000/rs6000.md: (constant splitters): Use "(pc)" as the replacements.
