bool markRangeAsAllCounted (uptr From, uptr To, uptr Base, const uptr RegionIndex, const uptr RegionSize)

Mark all the blocks in the given range [From, to). Instead of visiting all

the blocks, we will just mark the page as all counted. Note the `From` and

`To` has to be page aligned but with one exception, if `To` is equal to the

RegionSize, it's not necessary to be aligned with page size.
