Guozhi Wei 6599961c17 [TwoAddressInstructionPass] Improve the SrcRegMap and DstRegMap computation 
This patch contains following enhancements to SrcRegMap and DstRegMap:

  1 In findOnlyInterestingUse not only check if the Reg is two address usage,
    but also check after commutation can it be two address usage.

  2 If a physical register is clobbered, remove SrcRegMap entries that are
    mapped to it.

  3 In processTiedPairs, when create a new COPY instruction, add a SrcRegMap
    entry only when the COPY instruction is coalescable. (The COPY src is
    killed)

With these enhancements isProfitableToCommute can do better commute decision,
and finally more register copies are removed.
