Signal a compile-time error if a const constructor redirects to a
non-const constructor.

This CL also slightly improves the quality of the error message for
when a const constructor redirects to a non-const super constructor.

Note the two redirection checks are implemented in separate parts of
the code base. The former is implemented in finishConstructors in
kernel_target.dart, whilst the latter is implemented in
buildSuperInitializer in body_builder.dart. It might make sense to
localise them.
