Log:
    PR rtl-optimization/54870
    * tree.h (TREE_ADDRESSABLE): Document special usage on SSA_NAME.
    * cfgexpand.c (update_alias_info_with_stack_vars ): Set it on the
    SSA_NAME pointer that points to a partition if there is at least
    one variable with it set in the partition.
    * dse.c (local_variable_can_escape): New predicate.
    (can_escape): Call it.
    * gimplify.c (mark_addressable): If this is a partitioned decl, also
    mark the SSA_NAME pointer that points to a partition.
