Over on the AArch64/ARM side, Mike Stump mentioned that he would prefer the now-failing search for consume semantics to be marked XFAIL, rather than for us to update the testcase to reflect the promotion. https://gcc.gnu.org/ml/gcc-patches/2015-01/msg02517.html I'm not sure if that changes the approach you want to take for PowerPC, personally I don't have an opinion either way.
