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!

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

cf51f31c3e Add patterns for (mov R, R) (mov R, I) and subtracts. The moves are to enable 
testing, the subtracts are because I was in the neighborhood.

96704b97ca * Sort #includes, remove dupliates 
* Use .zero to emit padding between struct elements
* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.

  so it wasn't breaking anything, but it should be fixed anyway...
