Eventually, these hints should probably be moved over to warnings. But
for now, this makes it possible to write static error language tests
that validate that analyzer produces unreachable case warnings/hints
where expected.
Also updated the patterns/ and switch/ tests now that those errors must
be expected by the test.

Even when a switch case only contains a constant (and not some more
complex pattern), Dart 3.0 changes the semantics and allows constants
of types that don't have primitive equality.
Add some tests for that.

New language features made `futureOr(null) = 1` a syntactically
correct pattern assignment, so it should not be expected to cause a
syntax error. This CL changes that test case such that it is still an
assignment to a syntactically correct function invocation, but not a
correct pattern assignment (so it's again a syntax error).
Added more tests with similar properties: The 3.0 grammar causes some
test cases to be wrong, and this CL makes changes such that they will
continue to test "the same thing" as far as possible in the new
language.

The error has not been thrown since Dart 2.0,
where being able to reach the end of a switch case
became a compile-time error.
