6000 * gcse.c: Include df.h for use as a dataflow analyzer.
6002 Declaration of reg_set_info: gone.
6003 New df_analyzer variable used by store motion.
6004 (reg_set_info): Deleted.
6005 (mark_mem_regs): New function, analyze regs used by a mem.
6006 (store_ops_ok): Use dataflow analyzer results to determine if
6007 necessary regs are changed in the block.
6008 (find_moveable_store): Remove check for symbol ref, we can handle
6009 much more complex expressions now.
6010 (compute_store_table): Remove most of the code, it's unnecessary
6011 now that the dataflow analyzer records the info for us.
6012 (store_killed_after): Add parameter to say whether to do the
6013 store_ops_okay test, used to speed up testing when we already know
6014 the answer, and just want to know if the store itself was killed.
6015 (build_store_vector): Largely rewritten to calculate the various
6016 vectors properly, and somewhat optimized.
6017 (store_motion): Init the df_analyzer, get REG_DEF chains.
6018 Also handle trapping expressions (since mems almost always trap)
6019 (simple_mem): Redefine what a simple mem is.
