	PR debug/87428
	PR debug/87362
	* 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.
