re PR tree-optimization/56756 (ICE: verify_ssa failed (definition in block n follows the use !))

PR tree-optimization/56756
* tree-ssa-loop-im.c (struct first_mem_ref_loc_1): New functor.
(first_mem_ref_loc): New.
(execute_sm): Place the load temporarily before a previous
access instead of in the latch edge to ensure its SSA dependencies
are defined at points dominating the load.
* gcc.dg/torture/pr56756.c: New testcase.
