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.

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.

Stop using the `Offset' variable, as we are cycling through the bits of a field
...
initializer and the loop index variable already carries the offset information
that we need.

output clean so that tests can automatically diff the output.

* Added comment as to why we are still ignoring predict and annul bits.

* Now outputting a static function getBinaryCodeForInstr() (JIT-accessible)
...
* For debugging purposes:
+ output the predefined bit pattern of the instruction
* Fixed inefficiency: only load an operand from MachineInstr once
* Bug fix: did not advance bit index when seeing named bit-fields "annul", "cc"
and "predict"
* Added a catch-all for non-supported instructions at the end of switch stmt.
