use pstate.am to mask off PC/NPC where it needs to +be

check writability of tlb cache entry before using
update tagaccess in places I forgot to
move the tlb privileged test up since it is higher priority

src/arch/sparc/faults.cc:
    save only 32 bits of PC/NPC if Pstate.am is set
src/arch/sparc/isa/decoder.isa:
    return only 32 bits of PC/NPC if Pstate.am is set
    increment cleanwin correctly
src/arch/sparc/tlb.cc:
    check writability of cache entry
    update tagaccess in a few more places
    move the privileged test up since it is higher priority
src/cpu/exetrace.cc:
    mask off upper bits of pc if pstate.am is set before comparing to legion
