KT-15017 Throwing exception in the end of inline suspend-functions lead to internal compiler error

Suspend function call with a reachable (alive) begin marker and unreachable (dead) end marker is an exit point for the corresponding coroutine. It isn't a suspension point, and doesn't introduce a new state in the coroutine FSM.
