I know people who have. I've only ever run compiled code on any Crays, and this a long while ago. I think the Y-MP had a 42 bit fast int data type... The main thing about those is that they're more or less one or two digit serial number machines, so sometimes it really IS a compiler bug. They're also vector machines in a way that I don't think SSE type things really are. The granularity of the vector operations for max throughput isn't cache line sized; it's bigger than that, and there are special vector registers, and funny pick'm choose'm registers, in imperfect recollection...
