Optimize Loaded Chunks Cache Lookups
Reduces number of instructions a chunk lookup does
when accessing the last chunk cache. This reduces amount of work and opcodes
and allows better inlining.

In lots of profiling comparisons, this optimization was able to reduce the
cost of repeated chunk lookups that hit the cache pretty significantly.
