        * tree.h (BLOCK_NONLOCALIZED_VARS, BLOCK_NUM_NONLOCALIZED_VARS,
        BLOCK_NONLOCALIZED_VAR): New macros.
        (tree_block): Add nonlocalized_vars.
        * dwarf2out.c (gen_formal_parameter_die, gen_variable_die,
gen_decl_die): Add
        origin argument; allow generation of die with origin at hand only.
        (gen_member_die, gen_type_die_with_usage, force_decl_die,
        declare_in_namespace, gen_namescpace_die, dwarf2out_decl): Update use
of gen_*.
        (gen_block_die): Fix checking for unused blocks.
        (process_scope_var): Break out from .... ; work with origins only.
        (decls_for_scope) ... here; process nonlocalized list.
        (dwarf2out_ignore_block): Look for nonlocalized vars.
        * tree-ssa-live.c (remove_unused_scope_block_p): Look for nonlocalized
vars.
        (dump_scope_block): Dump them.
        * tree-inline.c (remap_decls): Handle nonlocalized vars.
        (remap_block): Likewise.
        (can_be_nonlocal): New predicate.
        (copy_bind_expr, copy_gimple_bind): Update use of remap_block.
