`Ctor: CodePointer;`
`Obj: pointer;`
`VMT: pointer`

## Description

CallVoidConstructor calls the constructor of an object. Ctor is the address of the constructor, Obj is a pointer to the instance. If it is Nil, then a new instance is allocated. VMT is a pointer to the object's VMT. The return value is a pointer to the instance.

Note that this can only be used on constructors that require no arguments.

## Errors

If the constructor expects arguments, the stack may be corrupted.
