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.

f4ef4c881f All debug print statements are now output with the DEBUG() guard to make 
output clean so that tests can automatically diff the output.

3d194ac26b * Stop ignoring cc registers, since we actually use them in branches. 
* Added comment as to why we are still ignoring predict and annul bits.

9a886386a4 Add -o support for TableGen 
I figure that misha has done a lot of things on my todo list, the least I
can do is reciprocate a bit.  :)

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.
