Clemens Hammacher ac73e1d52b Reland "[test] Check for illegal uses of mjsunit methods"
This is a reland of a9e93572d4

Original change's description:
> [test] Check for illegal uses of mjsunit methods
> 
> The assertThrows and assertDoesNotThrow methods expect either a
> function to execute, or a string to eval. In several tests however we
> accidentally passed the *result* of the statement to be tested instead
> of the code.
> This CL adds check to catch such error early, and removes wrong uses.
> In most places, we do not need to use assertDoesNotThrow anyway,
> because exceptions are handled as test failures.
> 
> Drive-by: Unify catch syntax in mjsunit.js and make sure to propagate
> MjsUnitAssertionErrors correctly.
