Added a scheme to allow aux-data to be printed out for debugging. For this to work, immediate operands referring to aux-data must be identified as such in the instruction descriptor table using OPERAND_AUX4 (all are always 4 bytes).

Rewrote the compiled [dict update] so that it stores critical non-varying data in an aux-data value instead of a (shimmerable) literal. [Bug 1671001]
