Avoid losing MEM_REF offset in MEM_EXPR adjustment for stack slot sharing
When investigating PR111591 with respect to TBAA and stack slot sharing
I noticed we're eventually scrapping a [TARGET_]MEM_REF offset when
rewriting the VAR_DECL base of the MEM_EXPR to use a pointer to the
partition instead. The following makes sure to preserve that.
* emit-rtl.cc (set_mem_attributes_minus_bitpos): Preserve
the offset when rewriting an exising MEM_REF base for
stack slot sharing.
