Currently libjit implements only local register allocation which means
that any branch causes it to spill all the values computed in a block.
It is also is not able to do proper data-flow analysis to determine
what values are dead and what are not at the end of the block, so
sometimes it spills already dead values. So, yes, there is a lot to be
improved in its code generation.
