Subject: RFR(S):8188757:PPC64:Disable VSR52-63 in ppc.ad

Dear all,

Would you please review the following change in hs?
Bug: https://bugs.openjdk.java.net/browse/JDK-8188757
Webrev: http://cr.openjdk.java.net/~mhorie/8188757/webrev.00/

This change disables VSR52-63 because currently there is no support for these registers to be properly treated as nonvolatile.
Also, this change removes redundant logical or with 1u to enforce to use VSR32- registers in assembler_ppc.inline.hpp, which was done in my previous webrev for 8188139.

Best regards,
IBM Research - Tokyo
