Avoid verifier crash for quickened invoke on null.

When verifying an invoke-virtual-quick on a "null" instance, we can't infer the
class of the method being invoked. This CL handles this case and avoid a crash
due to a failed check in RegType::GetClass.

Also revert changes made to test 082-inline-execute since it succeeds with this
CL now.
