[PATCH] D29742: [XRay] Implement powerpc64le xray.

[Tim Shen via Phabricator via llvm-commits]

powerpc64 bigendian is not supported, but I believe that most logic can
be shared, except for xray_powerpc64.cc.

Also add a function InvalidateInstructionCache to xray_util.h, which is
copied from llvm/Support/Memory.cpp. I'm not sure if I need to add a unittest,
and I don't know how.
