Stop special-casing annul and predict bits (which are Sparc-specific anyway)

since those bits are now hard-coded in Sparc*.td files.

The CodeEmitterGenerator used to consider ANY uninitialized field as being an
...
operand (unless it's annul or predict). Now we only consider fields to be
operands if they are uninitialized AND used in the "Inst" field.

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.

initializer and the loop index variable already carries the offset information

* 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.
