PR tree-optimization/50904
* tree-ssa-loop-im.c (struct mem_ref): Remove vops member.
(MEM_ANALYZABLE): New.
(memory_references): Remove clobbered_vops and vop_ref_map
members, add all_refs_stored_in_loop member.
(memref_free): Adjust.
(mem_ref_alloc): Likewise.
(gather_mem_refs_stmt): Do not record clobbers, instead
record refs for unanalyzable stmts.
(gather_mem_refs_in_loops): Do not propagate clobbers.
(struct vop_to_refs_elt, vtoe_hash, vtoe_eq, vtoe_free,
record_vop_access, get_vop_accesses, get_vop_stores,
add_vop_ref_mapping): Remove.
(create_vop_ref_mapping_loop): Adjust to simply record all
stores.
(analyze_memory_references): Adjust.
(refs_independent_p): Check for not analyzable refs.
(can_sm_ref_p): Likewise.
(ref_indep_loop_p_1): Simplify.
(tree_ssa_lim_finalize): Adjust.
* tree-ssa-loop-im.c (stmt_cost): Simplify, use LIM_EXPENSIVE
rather than magic constants. Assign zero cost to PAREN_EXPR
and SSA_NAME copies. Assign cost proportional to the vector
size for vector constructors.
