 * Special values, not visible to script but used internally by the engine.
 * JSVAL_HOLE is a useful value for identifying a hole in an array.  It's also
 * used in the interpreter to represent "no exception pending".  In general it
 * can be used to represent "no value".
 * A JSVAL_HOLE can be cheaply converted to undefined without affecting any
 * other boolean (or special value) by masking out JSVAL_HOLE_FLAG.
 * JSVAL_ARETURN is used to throw asynchronous return for generator.close().
 * NB: SPECIAL_TO_JSVAL(2) is JSVAL_VOID (see jsapi.h).
