      Implement PR3495: local spiller optimization. The local spiller can now keep availability information over BB boundaries. It visits BB's in depth first order. After visiting a BB if it find a successor which has a single predecessor it visits the successor next without clearing the availability information. This allows the successor to omit reloads or change them into copies.

      MachineMemOperands. The pools are owned by MachineFunctions.
      
      This drastically reduces the number of calls to malloc/free made
      during the "Emit" phase of scheduling, as well as later phases
      in CodeGen. Combined with other changes, this speeds up the
      "instruction selection" phase of CodeGen by 10% in some cases.

      More local spiller complexity! · 0609ab64
      Evan Cheng authored
      If local spiller optimization turns some instruction into an identity copy, it will be removed. If the output register happens to be dead (and source is obviously killed), transfer the kill / dead information to last use / def in the same MBB.

      Yet another nasty spiller bug. · 7ca4a67c
      Evan Cheng authored
      %ecx = op
      store %cl<kill>, (addr)
      (addr) = op %al
      
      It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below.
