Fixes problems instantiating STL containers, in rebind
The fix in question is in `definition_hypothetical::remap`, where partially remapped ASTs are discarded. This isn't valid.
Reduces total error count to 459, with one error remaining in ENIGMA's parse.
Fixes `operator,` and virtual inheritance parse
Does not denote virutal inheritance. That is a to-do item, of low importance.
Reduces remaining errors to 457, although it's clear something new is amiss, as uncommenting the zero-error headers increases count past 500.
