Subject: [tuples][patch] Dead Store Elimination

Hi.
Two days ago I sent a patch with tuplifies simple dse.
This patch tuplifies pass_dse AND pass_simple_dse.
Tested on amd64-linux, no regression, several test cases fixed.

* tree-ssa-dse.c (execute_simple_dse): #if 0 removed, bitmap_empty_p condition added. (get_stmt_uid): Removed. (record_voperand_set): Arguments changed. (dse_initialize_block_local_data, memory_ssa_name_same, memory_address_same, get_kill_of_stmt_lhs, dse_possible_dead_store_p, dse_optimize_stmt, dse_record_phis, dse_finalize_block, tree_ssa_dse): Tuplified. * passes.c (init_optimization_passes): pass_simple_dse and pass_dse enabled. * testsuite/gcc.dg/tree-ssa/ssa-dse-10.c: {dg-final} changed. * testsuite/gcc.dg/tree-ssa/pr30375.c: {dg-final} changed.
