This adds support for handling exceptions between different frames of
one single interpreter activation. Frames are dropped until a local
handler is found. If none is found in the current activation then we
delegate to the existing stack unwinding mechanism to deal with multiple
activations interspersed with non-interpreter stack frames on the actual
machine stack.
