If Op is equal to array_lengthof, the lookup would be out of bounds, but we were only checking for greater than. I suspect nothing ever passes in the equal value because its a sentinel to mark the end of the builtin opcodes and not a real opcode.
So really this fix is just so that the code looks right and makes sense.

if (VT.isExtended()) return Expand;
// If a target-specific SDNode requires legalization, require the target
// to provide custom legalization for it.
- if (Op > array_lengthof(OpActions[0])) return Custom;
+ if (Op >= array_lengthof(OpActions[0])) return Custom;
return OpActions[(unsigned)VT.getSimpleVT().SimpleTy][Op];
