i965: Emit MOVs for neg/abs.
Necessary to avoid combining a bitcast and a modifier into a single operation. Otherwise if safe, the MOV should be removed by copy-propagation or register coalescing. With this and the next patch, there are only four changes in shader-db: all a single extra instruction. The code does something like mov a.w, -b.x and copy propagation doesn't work because it only handles no-op swizzles. Seems acceptable, given the known limitation of our copy propagation.
