Simple shape functions not counted in coverage when precompiled

[jondea]

When calling name on a shape, like this:

name(shape::Circle) = "Circle"

coverage says that it is not covered but it is called in tests. I also have the same problem when using coverage locally. However, we did not have this problem before we enabled precompile.

I think this is a Julia bug, and so should be reported there, but I'm a bit nervous that I'm wrong...
