DIV/REM by constants should always be expanded into mul/shift/etc. patterns. Unfortunately the ConstantHoisting pass runs too early at a point where the pattern isn't expanded yet. However after ConstantHoisting hoisted some immediate the result may not expand anymore. Also the hoisting typically doesn't make sense because it operates on immediates that will change completely during the expansion. Report DIV/REM as TCC_Free so ConstantHoisting will not touch them.
