ART: Promoted register may be wrong after the load of zero fp constant

Because of Dalvik byte code's lack of immediate typing,
the same vreg may be used in core, ref and fp operations.
To properly support GC, we must ensure that if a constant zero is loaded
into a fp view of a vreg, it must also be loaded into the core/ref view.
The code that was responsible for ensuring this failed to handle the case
of a vreg having a non-promoted fp view and a promoted core/ref view.
