        * tree-inline.c (expand_call_inline): When the location
        of the call is UNKNOWN_LOCATION use DECL_SOURCE_LOCATION
        or BUILTINS_LOCATION for the BLOCK_SOURCE_LOCATION of
        the inserted BLOCK to make inlined_function_outer_scope_p
        recognize it.
        * dwarf2out.c (add_call_src_coords_attributes): Do not add
        coords for reserved locations.
