First, for reference, I was initially concerned the patterns were bogus,
but these are reasonably canonical ways to implement memset and the like.
I still think it would be better to fix the patterns by inserting an
UNSPEC. It's really not clear what set (BLK) (VOID) is supposed to mean.
Let's queue cleaning that up for GCC 7, unless you want to try and get
to it over the weekend. I don't know how many targets are affected offhand.
