/**

* <p>In order to simplify further processing, the opcodes passed
* to the visitor are canonicalized, altering the opcode to a more
* universal one and making formerly implicit arguments
* explicit. In particular:</p>
*
* <ul>
* <li>The opcodes to push literal constants of primitive types all become
* {@code ldc}.
* E.g., {@code fconst_0}, {@code sipush}, and
* {@code lconst_0} qualify for this treatment.</li>
* <li>{@code aconst_null} becomes {@code ldc} of a
* "known null."</li>
* <li>Shorthand local variable accessors become the corresponding
* longhand. E.g. {@code aload_2} becomes {@code aload}.</li>
* <li>{@code goto_w} and {@code jsr_w} become {@code goto}
* and {@code jsr} (respectively).</li>
* <li>{@code ldc_w} becomes {@code ldc}.</li>
* <li>{@code tableswitch} becomes {@code lookupswitch}.
* <li>Arithmetic, array, and value-returning ops are collapsed
* to the {@code int} variant opcode, with the {@code type}
* argument set to indicate the actual type. E.g.,
* {@code fadd} becomes {@code iadd}, but
* {@code type} is passed as {@code Type.FLOAT} in that
* case. Similarly, {@code areturn} becomes
* {@code ireturn}. (However, {@code return} remains
* unchanged.</li>
* <li>Local variable access ops are collapsed to the {@code int}
* variant opcode, with the {@code type} argument set to indicate
* the actual type. E.g., {@code aload} becomes {@code iload},
* but {@code type} is passed as {@code Type.OBJECT} in
* that case.</li>
* <li>Numeric conversion ops ({@code i2l}, etc.) are left alone
* to avoid too much confustion, but their {@code type} is
* the pushed type. E.g., {@code i2b} gets type
* {@code Type.INT}, and {@code f2d} gets type
* {@code Type.DOUBLE}. Other unaltered opcodes also get
* their pushed type. E.g., {@code arraylength} gets type
* {@code Type.INT}.</li>
