Rather than rely on recursion during the middle of register allocation, lower indirect registers to loads and stores off the indirect base into plain temps. For an x86_64 host, with sufficient registers, this results in identical code, modulo the actual register assignments. For an i686 host, with insufficient registers, this means that temps can be (temporarily) spilled to the stack in order to satisfy an allocation. This as opposed to the possibility of not being able to spill, to allocate a register for the indirect base, in order to perform a spill.
