re PR c++/80075 (ICE: "statement marked for throw, but doesn’t" with -fnon-call-exceptions)

2017-03-17  Richard Biener  <rguenther@suse.de>

	PR middle-end/80075
	* tree-eh.c (stmt_could_throw_1_p): Only handle gimple assigns.
	Properly verify the LHS before the RHS possibly claims to be
	handled.
	(stmt_could_throw_p): Hande gimple conds fully here.  Clobbers
	do not throw.

	* g++.dg/torture/pr80075.C: New testcase.
