Davide Italiano 329c83f959 [SCCP] Add a test for switches on undef. ...

Without this test, you can just remove the code fixing the
switch to the first constant in ResolvedUndefs in and everything
pass. This test, instead, fails with an assertion if the code
is removed. Found while refactoring SCCP to integrate undef in
the solver.
