Hi,
while looking into streamer code I noticed that I forgot to update it whole introducing
const_value_known flag.  Testing TREE_READONLY is also fine, but it leads us to stream
unnecesary many constructors.
Fixed thus. Boostrapped/regtested x86_64-linux, will commit it shortly.

	* lto.c (lto_promote_cross_file_statics): Use const_value_known.
	* lto-cgraph.c (compute_ltrans_boundary): Likewise.
