Consolidate test usage of ExpressionChecks.nullCheck into a single method.

This should make it easier to refactor the migration logic without
having to change tests too much.

Note that there is a minor loss of test coverage: in
test_functionInvocation_parameter_fromLocalParameter, we no longer
verify that non-null intent is sufficent to force a check to occur.
This is ok, because in future CLs, we will be simplifying the logic
for deciding when to add null checks so that it occurs precisely when
it's necessary to avoid a type mismatch.  Once that change has been
made, the correct behavior with non-null intent will happen
automatically.
