Split out test_incompat tests and added a few more cases

Browse Source 
Unlike the other test_compat tests, the test_incompat tests cover
specific corner cases and don't require any special linking. We probably
always want to run these, and keeping them merged with test_compat risks
the entire suite being omitted at some point.

The test_compat tests are a bit special and probably deserves a
dedicated test suite.
