re PR rtl-optimization/82044 (runtime signed integer overflow in check_mem_read_rtx() and all_positions_needed_p() in dse.c)

PR rtl-optimization/82044
PR tree-optimization/82042
* dse.c (record_store): Check for overflow.
(check_mem_read_rtx): Properly check for overflow if width == -1, call
add_wild_read instead of clear_rhs_from_active_local_stores on
overflow and log it into dump_file.
