* tree-ssa-dse.c (dse_classify_store): Remove use_stmt parameter,
add by_clobber_p one. Change algorithm to collect all defs
representing uses we need to walk and try reducing them to
a single one before failing.
(dse_dom_walker::dse_optimize_stmt): Adjust.
* gcc.dg/tree-ssa/ssa-dse-31.c: New testcase.
