Swap mg and eg in internal representation of Score Instrumentation shows that in make_score(mg, eg) calls, the mg value is zero in 25,9% of the calls while the eg value is zero in 36,8% of the calls. Swapping the internal fields of mg and eg in the internal representation of Score allows the compiler to optimize away the shift in (eg << 16) + mg in more cases, thus resulting in a 0.3% speed-up overall.
