b7803ab974 + llvm support for the register allocator. While llvm works with virtual 
registers itself, it requires them to be in SSA form. Therefore we
    spill all registers that are written more than once to memory.
  + support in the generic register allocator for generating code that is
    SSA-safe
  + spilling helpers for llvm
