* gimple-ssa-store-merging.c: Include gimplify-me.h.
(imm_store_chain_info::output_merged_stores): Force base_addr
to be proper GIMPLE for a MEM_REF address.
(pass_store_merging::execute): Restrict negative bitpos
handling to non-MEM_REF bases. Remove TREE_THIS_VOLATILE
check. Take into account non-NULL_TREE offset if the base
is already addressable.
* gcc.dg/store_merging_8.c: New testcase.
