Alexander Markov 8363860ee7 [vm,compiler] Fix handling of the argument of _simpleInstanceOf ...

The 2nd argument of _simpleInstanceOf call is always a
Constant (type). However, a Redefinition can be inserted in the middle.

So, instead of ArgumentAt(1)->AsConstant()->value() it is
more safe to use ArgumentValueAt(1)->BoundConstant() as
BindsToConstant/BoundConstant unwraps Redefinition(s) via
OriginalDefinition().
