Should be quite a bit simpler now, and no longer wastes ~4MB of
translation cache for aggressive block expiring. However more stuff
in cache means longer lists which may slow things down if
recompilation is happening nonstop, so further tuning might be needed.

Not sure why it was done the way it was (maybe something N64 related?),
but it occasionally caused dyna_linker to repeatedly walk the jump_in
list. What's worse, if the dirty block was deemed to expire soon,
it would never be restored and dyna_linker repeated jump_in walking
would never end, causing severe slowdown.
