SI-7008 @throws annotations are now populated in reflect

Runtime reflection in JavaMirrors previously forgot to fill in
@throws when importing Java reflection artifacts. Now this is fixed.

Note that generic exception types used in `throws` specifications will
be garbled (i.e. erased), because we don't use `getGenericExceptionTypes`
in favor of just `getExceptionTypes` to stay compatible with the behavior
of ClassfileParser. That's a bug, but a separate one and should be fixed
separately.

Also note that this commit updated javac-artifacts.jar, because we need
to test how reflection works with javac-produced classfiles. The sources
that were used to produce those classfiles can be found in the jar next
to the classfiles.
