re PR rtl-optimization/54870 (gfortran.dg/array_constructor_4.f90 FAILs)
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. From-SVN: r192517
