This test fails with the original patch, but this problem can be solved
by setting the storage class a bit earlier even without setting the
correct DeclContext. I have yet to come up with a test case that exposes
the wrong DeclContext.

I've restructured the patch to look at the parsed attributes to get the
correct DeclContext. Another option I explored was using setDeclContext
on the VarDecl. This passes all tests but I'm more reluctant to do this.
