Returns the exception handler types associated with this block, if any. This is just a
shorthand for inspecting the last instruction in the block to see if it could throw, and if so,
grabbing the catch list out of it. If not, this returns an empty list (not {@code null}).

@return {@code non-null;} the exception handler types associated with this block
