Basic work towards supporting ASIs properly

Browse source 
src/arch/sparc/SConscript:
    Added a file that implements ASI utility functions. These don't go in utility.hh because they aren't supposed to be part of the generic ISA interface.
src/arch/sparc/asi.hh:
    Fixed up some mistranscriptions, and added function prototypes for some ASI utility functions.
src/arch/sparc/asi.cc:
    Implementation of some ASI utility functions.
