Moves the context chain search loop out of generated bytecode, and into the (Lda|Ldr|Sda)ContextSlot handler, by passing the context depth in as an additional operand. This should decrease the bytecode size and increase performance for deep context chain searches, at the cost of slightly increasing bytecode size for shallow context access.
