Add some more tests.
- Mixing both kinds of mismatches: Done (test8)
- A case with uwind-to-caller and block signature needed: it's not possible because of newly added `rethrow`. Added a test that shows why it's not possible. (test7)
- Multiple nesting of mismatches: test8 kind of covers this too.

Note that `-wasm-disable-ehpad-sort` is used to generate maximum # of mismatches for those mismatch tests.
