RFR (XS): 8033117: PPC64: Adapt to 8002074: Support for AES on SPARC

[Lindenmaier, Goetz]

Hi,

The ppc port must implement Matcher::pass_original_key_for_aes() introduced to
jdk9 after the last merge to the staging repo.

Please review
http://cr.openjdk.java.net/~goetz/webrevs/8033117-1-aes/
for jdk9/hs-comp and also for downport to ppc-aix-port/stage which will
be integrated to jdk8u at some point.

The change affects only ppc64 files.

Thanks and best regards,
  Goetz.
