That then still shows problems with the pure function and -O2, but with
standard
C++ this then works:
struct S {
int foo(int i) const { if (i) throw 42; return 0; }
};
int __attribute__((noinline)) bar2

Classically it needs two DCE passes, the first removes the call LHS, the second
then no longer considers the call necessary because of EH. But even with that
fixed there are subsequent passes breaking thin
