g:6647c1e86f3b311d906a19b85182eed010ec03cf, r9-5008
This is an older failure that I previously missed. It only seems to occur on
power 7 BE so it may just be something not supported there.
testgcc: make -k check-gcc RUNTESTFLAGS=vect.exp=gcc.dg/vect/slp-perm-12.c

The actual update that started this is probably this one,
g:c9aa91088d2ab49a29c5588f62657afd7a84139, r9-5006, which won't compile.
