David Majnemer a1b821fac9 [LICM] Don't try to sink values out of loops without any exits ... There is no suitable basic block to sink instructions in loops without exits. The only way an instruction in a loop without exits can be used is as an incoming value to a PHI. In such cases, the incoming block for the corresponding value is unreachable. This fixes PR24013.
