  r221058 "[mips] Fix unused variable warning introduced in r221056"
  r221059 "[mips] Move all ByVal handling into CCState and tablegen-erated code. NFC."
  r221061 "Renamed CCState members that appear to misspell 'Processed' as 'Proceed'. NFC."

It cuased an undefined behavior in LLVM :: CodeGen/Mips/return-vector.ll.
