unsafe.SliceData can return pointers which are nil. That function gets lowered to the SSA OpSlicePtr, which the compiler assumes is non-nil. This used to be the case as OpSlicePtr was only used in situations where the bounds check already passed. But with unsafe.SliceData that is no longer the case. There are situations where we know it is nil. Use Bounded() to indicate that. I looked through all the uses of OSPTR and added SetBounded where it made sense. Most OSPTR results are passed directly to runtime calls (e.g. memmove), so even if we know they are non-nil that info isn't helpful.
