1/3 removes the unused xor argument to encode functions. This argument
is deadweight and its removal shaves off a both a few cycles per call as
well as a small amount of lines.

2/3 moves handling for cbc mode decryption to assembly in order to
remove overhead, yielding a ~6% speedup on AMD Zen1.

3/3 makes a minor readability change that doesn't fit well into 2/3.

  crypto: x86/twofish-3way - Perform cbc xor in assembly
  crypto: x86/twofish-3way - Remove unused macro argument
