[PATCH v2 13/18] convert LTO to automatic dependencies

[Tom Tromey]

This converts LTO.

This also fixes a latent buglet in lto/Make-lang.in.  lto_OBJS should
hold all the objects for a language, but LTO never defined this.

	* Make-lang.in (LTO_H, LINKER_PLUGIN_API_H, LTO_TREE_H)
	(lto/lto-lang.o, lto/lto.o, lto/lto-partition.o)
	(lto/lto-object.o): Remove.
