f6e5217b54 Fixed a bug: outputting name of variable instead of its value. 
Also, placed DEBUG() guards around debug information so that the generated file
is much smaller and hence should be faster to preprocess/compile.

7eac4766b1 This optimization greatly enhances efficiency of creating new instructions by 
masking and shifting operands directly into their place in the instruction,
instead of the old-fashioned way of ORing in each bit separately.

  and "predict"
* Added a catch-all for non-supported instructions at the end of switch stmt.
