Task Summary:
Optimize away shadow stack operations

Original Comment:
Recursion incurs push and restore on the shadow stack of all function parameters that are reference types. These shadow stack operations are costly and should be hoisted from inner loops that use arrays. This will make them up to 4x faster.
