This makes construction of Utf16String fallible in OOM conditions. The immediate impact is that PrimitiveString must then be fallible as well, as it may either transcode UTF-8 to UTF-16, or create a UTF-16 string from ropes. There are a couple of places where it is very non-trivial to propagate the error further. A FIXME has been added to those locations.
