These tests would not be the first in the test-suite to run FileCheck over
the output of -ast-print. That kind of test (while not ideal) seems much
better than making large changes with no test coverage. That obviously
won't check whether the source location is correct, but it will check
whether it's valid in the right set of circumstances.
