This is not quite NFC: we don't perform the usual arithmetic conversions unless we have an operand of arithmetic or enumeration type any more. This matches the standard rule, but actually has no effect other than to marginally improve our diagnostics for the non-arithmetic, non-enumeration cases (by not performing integral promotions on one operand if the other is a pointer). llvm-svn: 322024
