It's completely unnecessary and can be replace with proper SReg_64 handling instead. This actually fixes a piglit test on SI. v2: use correct register class in addRegisterClass, set special classes as not allocatable v3: revert setting special classes as not allocateable This is a candidate for the stable branch.
