Add extra step for DDC library bundle format

dart-lang/sdk@6127d6c
adds an extra check to avoid emitting extra runtime checks
if the hot reload generation hasn't changed. One of the
breakpoint tests relies on the JS location of the Dart code
being the location right before the function call, but that
needs to be updated to step past that extra check.
