tcg/optimize: fix if/else/break coding style
optimizer.c contains some cases were the break is appearing in both the if and the else parts. Fix that by moving it to the outer part. Also move some common code there. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
