* A jsval has an abstract type which is represented by a mask which assigns a
* bit to each type. This allows fast set-membership queries. However, we give
* one type (null) a mask of 0 for two reasons:
* 1. memset'ing values to 0 produces a valid value. This was true of the old,
* boxed jsvals (and now jsboxedwords) and eases the transition.
* 2. Testing for null can often be compiled to slightly shorter/faster code.
*
* The down-side is that set-membership queries need to be done more carefully.
* E.g., to test whether a value v is undefined or null, the correct test is:
* (v.mask & ~UndefinedMask) == 0
* instead of the intuitive (but incorrect) test:
* (v.mask & (NullMask | UndefinedMask)) != 0
* Since the value representation is kept a private detail of js::Value and
* only exposed to a few functions through friendship, this type of error
* should be hidden behind simple inline methods like v.isNullOrUndefined().
