        (free_csa_reflist): ... this.
        (record_one_stack_memref): Rename to...
        (record_one_stack_ref): ... this.  Handle also REG_P.

        (struct record_stack_refs_data): ... this.  Rename memlist field to
        reflist.
        (record_stack_memrefs): Rename to...
        (record_stack_refs): ... this.  For DEBUG_INSNs keep traversing
        subexpressions instead of failing when a MEM contains SP references.
        For SP itself in DEBUG_INSNs queue it also onto reflist chain.
        (combine_stack_adjustments_for_block): Adjust for mem to ref renaming.
