[TargetLowering] Stop passing an ISD::CondCode to isOperationLegalOrCustom.

[craig.topper]

Summary

ISD::CondCode is a separate num space from opcodes. isOperationLegalOrCustom
should take an opcode.

Should this check SETCCVT instead? SETEQ is created below with this type.

TargetLowering::prepareSREMEqFold(EVT SETCCVT, SDValue REMNode,
   // That fold is only valid for positive divisors. Which effectively means,
   // it is invalid for INT_MIN divisors. So if we have such a lane,
   // we must fix-up results for said lanes.
   assert(VT.isVector() && "Can/should only get here for vectors.");
 
   // NOTE: we avoid letting illegal types through even if we're before legalize
   // ops – legalization has a hard time producing good code for the code that
   // follows.
