[PATCH] [Mips] Handle -mips32r[3|5] / -mips64r[3|5] options while selecting lib/headers paths

[Daniel Sanders]

LGTM if that's formatted how clang-format would do it. Otherwise LGTM with the formatting nit fixed.

----------------
Nit: Is this what clang-format would do? I would have expected:

  addMultilibFlag(
      CPUName == "mips32r2" || CPUName == "mips32r3" || CPUName == "mips32r5",
      "march=mips32r2", Flags);
