- 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.

- 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.
