Move around misc reg code
src/arch/sparc/faults.cc: Moved some code here from miscregfile.cc src/arch/sparc/miscregfile.cc: Moved code from here to faults.cc, and merged (read|set)MiscRegWithEffect and it's FS version from ua2005.cc src/arch/sparc/miscregfile.hh: readFSRegWithEffect is no longer a seperate function, and is instead done in the main readRegWith Effect. --HG-- extra : convert_revision : 0b45f0f78e83929b32ddd2f443c8b1dbf9bc04fb
