I think we should implement whatever OpenCL specs and disregard whatever the (dead) Cell C/C++ language docs say. The project is to improve GCCs generic vector facility, not to implement the Cell language spec. But of course the above could be a pedwarn (though you'll get stmt verification errors if you build a BIT_FIELD_REF with out-of-bounds indices - so we'd need to emit sth like a zero index for out-of-bound accesses).
