Agreed for the GCC 6 part and desire to reapply the cse.c change for GCC 7,
what exactly we should do for the AVX stuff in GCC 7 is unclear, it might be
some change in the patterns, or some target specific pass (e.g. we have the stv
pass after combiner, so there could be another one that attempts to un-CSE
constant zero vectors if used with 0C constraints, whatever).
