Should panic with specific message

[LHerskind]

Problem

When testing it can be very useful to test that a failure was due to a specific assertion. From #1994 it is possible to test failing cases, but it is not giving much input on exactly why it failed. Adding this feature could be very useful for more complete testing. Depends on #1939 to be included first.

Happy Case

Adding support for something like

#[test(should_fail_with("assert message")]

Would be neat.
