	PR c++/71210
	* gimple-fold.c (gimple_fold_call): Do not remove lhs of noreturn
	calls if the LHS is variable length or has addressable type.
	If targets[0]->decl is a noreturn call with void return type and
	zero arguments, adjust fntype and remove lhs in that case.

	* g++.dg/opt/pr71210-1.C: New test.
	* g++.dg/opt/pr71210-2.C: New test.
