commit 321771ee63740333ad355244e0764295218843b8
Author: Mark Wielaard <mark@klomp.org>
Date: Sun Dec 9 14:26:39 2018 +0100
memcheck: Allow unaligned loads of 128bit vectors on ppc64[le].
On powerpc partial unaligned loads of vectors from partially invalid
addresses are OK and could be generated by our translation of lxvd2x.
Adjust partial_load memcheck tests to allow partial loads of 16 byte
vectors on powerpc64.
Part of resolving bug #386945.
