JitCache has been using a class called ValidBlockBitSet. This commit replaces it with a new class called LazyMemoryRegionBitSet, which works similarly but is backed by a LazyMemoryRegion, letting us skip allocating memory for parts of the bit set that correspond to emulated memory regions where the game isn't storing any code. I have also added optimized functions for setting or clearing long runs of bits. Additionally, this commit replaces JitBase's three std::unordered_sets that are keeping track of instructions with LazyMemoryRegionBitSets. Here the benefit is more speed than memory usage. This improves NBA Live 2005's menu performance by 1% or so in SuperSamus's testing.
