We can't skip `cf.assert` as this is shared code, but I've now reworked things so you can specify the runtime function to use. `cf.assert` will now keep using `puts()` and `vector.print` will use a new `printString()` function (which is defined only in CRunnerUtils).

`printCString()` should be removed in a later patch (and uses updated to use `vector.print str` or `printString()` directly)
