	redundant val and dest members.

	(merged_store_group::merged_store_group): Adjust.
	(merged_store_group::apply_stores): Likewise.
	(struct imm_store_chain_info): Add base_addr field.
	(imm_store_chain_info::imm_store_chain_info): New constructor.
	(imm_store_chain_info::terminate_and_process_chain): Do not pass base.

	(imm_store_chain_info::output_merged_stores): Likewise.
	(pass_tree_store_merging::terminate_all_aliasing_chains): Take
	imm_store_chain_info instead of base.  Fix alias check.
	(pass_tree_store_merging::terminate_and_release_chain): Likewise.
	(imm_store_chain_info::coalesce_immediate_stores): Adjust.
