Subject: [PATCH] [ArgumentPromotion] Remove unnecessary getScalarType() before
 casting to PointerType. NFC

I don't believe this pass deals with vectors of pointers. I think
this getScalarType() was added during a mechanical opaque pointer
change of the interface to GetElementPtrInst::getIndexedType.
