Detailed Description

Code dealing with scratches (changing them onto
pseudos and restoring them from the pseudos).

We change scratches into pseudos at the beginning of IRA to
simplify dealing with them (conflicts, hard register assignments).

If the pseudo denoting scratch was spilled it means that we do not
need a hard register for it.  Such pseudos are transformed back to
scratches at the end of LRA.   

Description of location of a former scratch operand.
