b047a0d449 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

8cedc4ffa6 * Removed `using' declaration, now use full namespace qualifier std::string

7452a521b3 Stop special-casing annul and predict bits (which are Sparc-specific anyway) 
since those bits are now hard-coded in Sparc*.td files.

c666ae831c * Set annul bit to be 0, because the Sparc backend currently does not use it. 
* Use the name of the predict field instead of just the const 1 in the
  Instruction.

d8cbdc4c67 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.

17fc21b5fa This is the real fix for the previous register allocator problem. 
Physical registers should not float around.

testing, the subtracts are because I was in the neighborhood.

08f4aa071b * Don't print out HOW we are running Flex unless in verbose mode. We already 
hide the bison command line.
* If running flex or bison gives us the files we already have, don't overwrite
  the ones we have, which cause unnecessary compilation.  I demand the ability
  to make meaningless changes without penalty!
