      * method in API_OLD is deprecated and replaced with visitNewStuff in API_NEW, then the
      * redirection should be done as follows:
      *
      * <pre>
      * public class StuffVisitor {
      *   ...
      *
      *   &#64;Deprecated public void visitOldStuff(int arg, ...) {

      *       [ do stuff ]
      *     }
      *   }
      * }
      * </pre>
      *
      * <p>If 'api' is equal to API_NEW, there are two cases:
      *
      * <ul>
      *   <li>call visitNewStuff: the redirection test is skipped and 'do stuff' is executed directly.
      *   <li>call visitOldSuff: the source is not set to SOURCE_DEPRECATED before calling
      *       visitNewStuff, but the redirection test is skipped anyway in visitNewStuff, which
      *       directly executes 'do stuff'.
      * </ul>
      *
      * <p>If 'api' is equal to API_OLD, there are two cases:
      *
      * <ul>
      *   <li>call visitOldSuff: the source is set to SOURCE_DEPRECATED before calling visitNewStuff.
      *       Because of this visitNewStuff does not redirect back to visitOldStuff, and instead
      *       executes 'do stuff'.
      *   <li>call visitNewStuff: the call is redirected to visitOldStuff because the source is 0.
      *       visitOldStuff now sets the source to SOURCE_DEPRECATED and calls visitNewStuff back. This
      *       time visitNewStuff does not redirect the call, and instead executes 'do stuff'.
      * </ul>
      *
      * <h1>User subclasses</h1>
      *
      * <p>If a user subclass overrides one of these methods, there are only two cases: either 'api' is
      * API_OLD and visitOldStuff is overridden (and visitNewStuff is not), or 'api' is API_NEW or
      * more, and visitNewStuff is overridden (and visitOldStuff is not). Any other case is a user
      * programming error.
      *
      * <p>If 'api' is equal to API_NEW, the class hierarchy is equivalent to
      *
      * <pre>
      * public class StuffVisitor {
      *   &#64;Deprecated public void visitOldStuff(int arg, ...) { visitNewStuf(arg, ...); }
      *   public void visitNewStuff(int arg, ...) { [ do stuff ] }
      * }
      * class UserStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitNewStuff(int arg, ...) {
      *     super.visitNewStuff(int arg, ...); // optional
      *     [ do user stuff ]
      *   }
      * }
      * </pre>
      *
      * <p>It is then obvious that whether visitNewStuff or visitOldStuff is called, 'do stuff' and 'do
      * user stuff' will be executed, in this order.
      *
      * <p>If 'api' is equal to API_OLD, the class hierarchy is equivalent to
      *
      * <pre>
      * public class StuffVisitor {
      *   &#64;Deprecated public void visitOldStuff(int arg, ...) {
      *     visitNewStuf(arg | SOURCE_DEPRECATED, ...);
      *   }
      *   public void visitNewStuff(int argAndSource...) {
      *     if ((argAndSource & SOURCE_DEPRECATED) == 0) {
      *       visitOldStuff(argAndSource, ...);
      *     } else {
      *       int arg = argAndSource &#38; ~SOURCE_MASK;
      *       [ do stuff ]
      *     }
      *   }
      * }
      * class UserStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitOldStuff(int arg, ...) {
      *     super.visitOldStuff(int arg, ...); // optional
      *     [ do user stuff ]
      *   }
      * }
      * </pre>
      *
      * <p>and there are two cases:
      *
      * <ul>
      *   <li>call visitOldSuff: in the call to super.visitOldStuff, the source is set to
      *       SOURCE_DEPRECATED and visitNewStuff is called. Here 'do stuff' is run because the source
      *       was previously set to SOURCE_DEPRECATED, and execution eventually returns to
      *       UserStuffVisitor.visitOldStuff, where 'do user stuff' is run.
      *   <li>call visitNewStuff: the call is redirected to UserStuffVisitor.visitOldStuff because the
      *       source is 0. Execution continues as in the previous case, resulting in 'do stuff' and 'do
      *       user stuff' being executed, in this order.
      * </ul>
      *
      * <h1>ASM subclasses</h1>
      *
      * <p>In ASM packages, subclasses of StuffVisitor can typically be sub classed again by the user,
      * and can be used with API_OLD or API_NEW. Because of this, if such a subclass must override
      * visitNewStuff, it must do so in the following way (and must not override visitOldStuff):
      *
      * <pre>
      * public class AsmStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitNewStuff(int argAndSource, ...) {
      *     if (api &#60; API_NEW &#38;&#38; (argAndSource &#38; SOURCE_DEPRECATED) == 0) {
      *       super.visitNewStuff(argAndSource, ...);
      *       return;
      *     }
      *     super.visitNewStuff(argAndSource, ...); // optional
      *     int arg = argAndSource &#38; ~SOURCE_MASK;
      *     [ do other stuff ]
      *   }
      * }
      * </pre>
      *
      * <p>If a user class extends this with 'api' equal to API_NEW, the class hierarchy is equivalent
      * to
      *
      * <pre>
      * public class StuffVisitor {
      *   &#64;Deprecated public void visitOldStuff(int arg, ...) { visitNewStuf(arg, ...); }
      *   public void visitNewStuff(int arg, ...) { [ do stuff ] }
      * }
      * public class AsmStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitNewStuff(int arg, ...) {
      *     super.visitNewStuff(arg, ...);
      *     [ do other stuff ]
      *   }
      * }
      * class UserStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitNewStuff(int arg, ...) {
      *     super.visitNewStuff(int arg, ...);
      *     [ do user stuff ]
      *   }
      * }
      * </pre>
      *
      * <p>It is then obvious that whether visitNewStuff or visitOldStuff is called, 'do stuff', 'do
      * other stuff' and 'do user stuff' will be executed, in this order. If, on the other hand, a user
      * class extends AsmStuffVisitor with 'api' equal to API_OLD, the class hierarchy is equivalent to
      *
      * <pre>
      * public class StuffVisitor {
      *   &#64;Deprecated public void visitOldStuff(int arg, ...) {
      *     visitNewStuf(arg | SOURCE_DEPRECATED, ...);
      *   }
      *   public void visitNewStuff(int argAndSource, ...) {
      *     if ((argAndSource & SOURCE_DEPRECATED) == 0) {
      *       visitOldStuff(argAndSource, ...);
      *     } else {
      *       int arg = argAndSource &#38; ~SOURCE_MASK;
      *       [ do stuff ]
      *     }
      *   }
      * }
      * public class AsmStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitNewStuff(int argAndSource, ...) {
      *     if ((argAndSource &#38; SOURCE_DEPRECATED) == 0) {
      *       super.visitNewStuff(argAndSource, ...);
      *       return;
      *     }
      *     super.visitNewStuff(argAndSource, ...); // optional
      *     int arg = argAndSource &#38; ~SOURCE_MASK;
      *     [ do other stuff ]
      *   }
      * }
      * class UserStuffVisitor extends StuffVisitor {
      *   &#64;Override public void visitOldStuff(int arg, ...) {
      *     super.visitOldStuff(arg, ...);
      *     [ do user stuff ]
      *   }
      * }
      * </pre>
      *
      * <p>and, here again, whether visitNewStuff or visitOldStuff is called, 'do stuff', 'do other
      * stuff' and 'do user stuff' will be executed, in this order (exercise left to the reader).
      *
      * <h1>Notes</h1>
      *
      * <ul>
      *   <li>the SOURCE_DEPRECATED flag is set only if 'api' is API_OLD, just before calling
      *       visitNewStuff. By hypothesis, this method is not overridden by the user. Therefore, user
      *       classes can never see this flag. Only ASM subclasses must take care of extracting the
      *       actual argument value by clearing the source flags.
      *   <li>because the SOURCE_DEPRECATED flag is immediately cleared in the caller, the caller can
      *       call visitOldStuff or visitNewStuff (in 'do stuff' and 'do user stuff') on a delegate
      *       visitor without any risks (breaking the redirection logic, "leaking" the flag, etc).
      *   <li>all the scenarios discussed above are unit tested in MethodVisitorTest.
      * </ul>
