For CompareOperations, we only care about Null or Undefined feedback
for oddballs. Other oddballs like Booleans should be treated as "Any"
feedback. There was a bug in the way we handled feedback when lhs is
undefined or null and rhs is anything other than JSReceiver. This cl
fixes it by removing an unnecessary check. This fixes a deopt loop in
TurboProp on maps benchmark.
