PR tree-optimization/84503
* gimple-ssa-store-merging.c (merged_store_group::merge_into): Compute
width as info->bitpos + info->bitsize - start.
(merged_store_group::merge_overlapping): Simplify width computation.
(check_no_overlap): New function.
(imm_store_chain_info::try_coalesce_bswap): Compute expected
start + width and last_order of the group, fail if check_no_overlap
fails.
(imm_store_chain_info::coalesce_immediate_stores): Don't merge info
to group if check_no_overlap fails.
* gcc.dg/pr84503-1.c: New test.
* gcc.dg/pr84503-2.c: New test.
