Revert incorrect fix for ASM bug 317127

The [fix][1] for ASM's bug 317127 leads to some InnerClass attributes
not being emitted. The problem has been reported as [317200][2].

This commit can be reverted once a fix is available.

Makes the ICode inliner work again on nsc.Global.assert. I haven't
checked in what way the Scala compiler relies on InnerClass attributes
in classfiles.
