extmod/re1.5: Fix compilecode.c compile problem on IAR tool chain.
The 2nd and 3rd args of the ternary operator are treated like they are in
the same expression and must have similar types.  void is not compatible
with int so that's why the compiler is complaining.
#include "re1.5.h"
#define INSERT_CODE(at, num, pc) \
- ((code ? memmove(code + at + num, code + at, pc - at) : (void)0), pc += num)

#define REL(at, to) (to - at - 2)
