Subject: [opaque pointer types] [NFC] GEP: replace get(Pointer)ElementType
 uses with get{Source,Result}ElementType.

Summary:
GEPOperator: provide getResultElementType alongside getSourceElementType.
This is made possible by adding a result element type field to GetElementPtrConstantExpr, which GetElementPtrInst already has.

GEP: replace get(Pointer)ElementType uses with get{Source,Result}ElementType.
