* gcse.c: Include df.h for use as a dataflow analyzer.
Remove regvec.
Declaration of reg_set_info: gone.

necessary regs are changed in the block.

much more complex expressions now.

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.

vectors properly, and somewhat optimized.
(store_motion): Init the df_analyzer, get REG_DEF chains.
Also handle trapping expressions (since mems almost always trap)
