re PR tree-optimization/51719 (ICE: verify_gimple failed: LHS in noreturn call with -fpartial-inlining -fprofile-use and exceptions)

	PR tree-optimization/51719
	* value-prof.c (gimple_ic): When indirect call isn't noreturn,
	but direct call is, clear direct call's lhs and don't add fallthrough
	edge from dcall_bb to join_bb and PHIs.

	* g++.dg/tree-prof/pr51719.C: New test.
