store-merging: Fix up -Wnarrowing warning

I've noticed a -Wnarrowing warning on gimple-ssa-store-merging.c, this
change fixes that up.

2020-10-05  Jakub Jelinek  <jakub@redhat.com>

	* gimple-ssa-store-merging.c
	(imm_store_chain_info::output_merged_store): Use ~0U instead of ~0 in
	unsigned int array initializer.
