Add a test that currently only reports if a non-abstract method
on primitive vector or species class is:
1) overridden by a method on a concrete implementation; or
2) is not overridden on a concrete implementation.
The first case implies the method can be abstract, the
second case may imply a missing intrinsic or is non-optimal
for the primtive type and shape.
