 * This explains what to do if you have a load past an ambiguous store if
 * SPEC_STALL, just don't issue the load if SPEC_LIMBO, issue the load, then
 * keep it in "limbo" state -- when all previous stores are disambiguated, you
 * then use the value of the load. If a previous store conflicts, you'll mark
 * the load as though it had never been issued.  if SPEC_EXCEPT, issue the
 * load. When it comes back, keep it in LoadQueue, but let its value go on to
 * subsequent instructions. If all previous stores are disambiguated, remove
 * the thing from the load queue. If a previous store conflicts, you'll mark
 * the load as a soft exception
