Add assertion in liveliness computation
Assert that a live-range does not start, while one for the same
variable is already active.
To satisfy this constraint, explicitly exclude writes from JMP_SET
and COALESCE. They were previously also handled correctly, because
their result variable was only killed after the second write to it
after the false branch. This just makes it more explicit.
