Cgraph alias reorg 11/14 (stream indirect call jump functions)

[Jan Hubicka]

Hi,
this patch fixes omission I noticed while debugging unrelated problem.  While
we compute jump functions for indirect calls (so they can possibly be used after
the indirect calls become direct) we forget to stream them.

Fixed thus. Regtested/bootstrapped x86_64-linux, will commit it shortly.

	* ipa-prop.c (ipa_write_node_info): Stream jump functions for indirect
	calls.
	(ipa_read_node_info): Likewise.
