Only allow writing/reading of 32 bits of Y
Only allow writing/reading 32 bits of pc when pstate.am
Put any loaded data on the first half of a micro-op in uReg0 so it can't
overwrite the register we are using for address calculation
only erase a entry from the lookup table if it's valid
Put in a temporary check to make sure that lookup table and tlb array stay in sync
if we are interrupted in the middle of a mico-op, reset the micropc/nexpc
so we start on the first part of it when we come back
src/arch/sparc/isa/decoder.isa:
fix smul and sdiv to sign extend, and handle overflow/underflow corretly

src/arch/sparc/isa/includes.isa:
Use limits for 32bit underflow/overflow detection
src/arch/sparc/tlb.cc:

Put in a temporary check to make sure that lookup table and tlb array stay in sync
src/arch/sparc/tlb_map.hh:
add a print function to dump the tlb lookup table
src/cpu/simple/base.cc:
if we are interrupted in the middle of a mico-op, reset the micropc/nexpc
so we start on the first part of it when we come back
