some small general fixes to make everythign work nicely with other ISAs, now we can merge back with newmem.

exetrace.cc:
wrap this variable between FULL_SYSTEM #ifs
mmaped_ipr.hh:
fix for build
miscregfile.cc:
fixes for HPSTATE access during SE mode

src/arch/sparc/miscregfile.cc:
    fixes for HPSTATE access during SE mode
src/arch/mips/mmaped_ipr.hh:
    fix for build
src/cpu/exetrace.cc:
    wrap this variable between FULL_SYSTEM #ifs
