thanks for implementing it and taking care of my concerns. Looks good, now.
I will run tests and I can sponsor it after it was reviewed.

Subject: RFR(M): PPC64: improve array copy stubs by using vector instructions
Could you please host and review this webrev?
* Add VSR registers to be used with VSX instruction set;
* Add VSX load/store instructions (lxvd2x/stxvd2x) to mass copy in
the stub for disjoint short copy in order to improve it.
