Rewrite to use buildSpillLoadStore.

This makes buildSpillLoadStore public and adds a new optional LivePhysRegs parameter, to find an unused register if we have no RegScavenger.
Now this patch merges buildPrologSpill and buildEpilogReload into buildSpillLoadStore and uses that function from emitProlog/emitEpilog.
