#403666.  Specifically,

In codestr, force `c' to be global.  It's unclear what the semantics
should be for a code object compiled at module scope, but bound and
run in a function.  In CPython, `c' is global (by accident?) while in
Jython, `c' is local.  The intent of the test clearly is to make `c'
global, so let's be explicit about it.

Jython also does not have a __builtins__ name in the module's
namespace, so we use a more portable alternative (though I'm not sure
why the test requires "__builtins__" in the g namespace).

Finally, skip the new.code() test if the new module doesn't have a
`code' attribute.  Jython will never have this.
