Summary: This wasn't noticed: `RoundUpTo` doesn't produce a constant expression, so the sizes were not constant either. Enforce them to be static const, replace `RoundUpTo` by its expression. The compiler can now optimize the associated computations accordingly. Also looking at the produced assembly, `PageSize` was fetched multiple times during `Allocate`, so keep a local value of it. As a result it's fetched once and kept in a register.
