* config/rs6000/power6.md: Replace store_data_bypass_p calls with
rs6000_store_data_bypass_p in seven define_bypass directives and
in several comments.
* config/rs6000/rs6000-protos.h: Add prototype for
rs6000_store_data_bypass_p function.
* config/rs6000/rs6000.c (rs6000_store_data_bypass_p): New
function implements slightly different (rs6000-specific) semantics
than store_data_bypass_p, returning false rather than aborting
with assertion error when arguments do not satisfy the
requirements of store data bypass.
(rs6000_adjust_cost): Replace six calls of store_data_bypass_p with
rs6000_store_data_bypass_p.
