* gcse.c: Include df.h for use as a dataflow analyzer.
Remove regvec.
Declaration of reg_set_info: gone.
New df_analyzer variable used by store motion.
(reg_set_info): Deleted.
(mark_mem_regs): New function, analyze regs used by a mem.

necessary regs are changed in the block.
(find_moveable_store): Remove check for symbol ref, we can handle
much more complex expressions now.
(compute_store_table): Remove most of the code, it's unnecessary
now that the dataflow analyzer records the info for us.
(store_killed_after): Add parameter to say whether to do the
store_ops_okay test, used to speed up testing when we already know
the answer, and just want to know if the store itself was killed.
(build_store_vector): Largely rewritten to calculate the various
vectors properly, and somewhat optimized.
(store_motion): Init the df_analyzer, get REG_DEF chains.
Also handle trapping expressions (since mems almost always trap)
