Take branching and method calls into account when finding the line
number of the continuation. If there is no line number before
branching instructions or method calls, the following code is
still on the line of the suspend call itself.
This fixes a couple of issues with incorrect line numbers for
multiple throws on the same line or multipe suspend calls on
the same line.
In addition, it avoids the need to spam the method node with
repeated line number instructions in the IR backend.
