I stumbled over this when looking into some ICEs with -g - we should
not find referenced vars in debug stmts.  Not that we should start
looking for -g vs. -g0 issues with LTO ...

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

	* lto-streamer-in.c (input_bb): Do not find referenced vars
	in debug statements.
