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.

48aa824279 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.

cbfde0a612 * 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.
