* mix expanded and compressed frames within a single method):
* <ul>
* <li>In expanded form, all frames must have the F_NEW type.</li>
* <li>In compressed form, frames are basically "deltas" from the state of
* the previous frame:

* <li>{@link Opcodes#F_SAME} representing frame with exactly the same

* type of the stack item).</li>
* <li>{@link Opcodes#F_APPEND} representing frame with current locals are
* the same as the locals in the previous frame, except that additional
* locals are defined (<code>nLocal</code> is 1, 2 or 3 and
* <code>local</code> elements contains values representing added types).</li>
* <li>{@link Opcodes#F_CHOP} representing frame with current locals are the
* same as the locals in the previous frame, except that the last 1-3 locals
* are absent and with the empty stack (<code>nLocals</code> is 1, 2 or 3).</li>

* and access flags, is implicit and must not be visited. Also, it is
* illegal to visit two or more frames for the same code location (i.e., at
* least one instruction must be visited between two calls to visitFrame).
*
* @param type
* the type of this stack map frame. Must be
