* JS string type implementation.
*
* In order to avoid unnecessary js_LockGCThing/js_UnlockGCThing calls, these
* native methods store strings (possibly newborn) converted from their 'this'
* parameter and arguments on the stack: 'this' conversions at argv[-1], arg
* conversions at their index (argv[0], argv[1]). This is a legitimate method
* of rooting things that might lose their newborn root due to subsequent GC

* 1 bit if 1, character has a titlecase equivalent (possibly itself)

* 7 may start a Unicode identifier

* 1 is ignorable within an identifier
* 4 is JS whitespace
* 2 bits 0 this character has no numeric property

* 2 this character has a "strange" numeric value
* 3 a JS supradecimal digit: adding the digit offset to the

* will produce the desired numeric value
* 5 bits digit offset
