* JS string type implementation.
|

*
|

* A JS string is a counted array of unicode characters. To support handoff
|
||||
* of API client memory, the chars are allocated separately from the length,
|
||||
* necessitating a pointer after the count, to form a string header. String
|
||||
* headers are GC'ed while string bytes are allocated from the malloc heap.
|

*
|
||||
* When a string is treated as an object (by following it with . or []), the
|
||||
* runtime wraps it with a JSObject whose valueOf method returns the unwrapped
|
||||
* string header.
