arguments objects are prototyped by Object.prototype, per ECMA. We still
want a custom class, in order to lazily resolve active-JSStackFrame-based
properties.
- Use a reserved slot to hold a bitmap of deleted arguments elements, so we
don't re-resolve them after they've been deleted (which would make them seem
to be permanent, contrary to ECMA). This work involved sprucing up several
fundamental types (jsbitmap) and macros (jsbitmap helper macros in jsbit.h,
JS_HOWMANY in jstypes.h, JSVAL_INT_BITS in jsapi.h).
