With the new AOT changes, it looks like IDIC casts to invalid WinRT interfaces cause a crash during helper type lookup due to the either triggering the fallback logic to init vtable in JIT or due to not being a valid helper type on AOT. But with IDIC, if they did an as operator, it shouldn't crash. Due to this, adding a check for if it is a WinRT type before going through the IDIC QI logic.
