object GenerateMutableProjection extends CodeGenerator[Seq[Expression], MutableProjection]
Generates byte code that produces a InternalRow object that can update itself based on a new
input InternalRow for a fixed set of Expressions.
It exposes a target method, which is used to set the row that will be updated.
The internal InternalRow object created internally is used only when target is not used.
