Fixed the priv instruction format.
src/arch/sparc/isa/formats/priv.isa: Fix the priv format so that it uses isa_parser operands rather than accessing the registers directly in checkCode. Also, the expressions needed to be negated. src/arch/sparc/isa/operands.isa: Added an Hpstate operand, and adjusted the numbering. --HG-- extra : convert_revision : 4a70862df061aa9e1b9eab125c4c2fc839ac3b5a
