isel used to require zero vectors to be canonicalized to a single type to minimize the number of patterns needed to match. This is no longer required. I plan to do this to integers too, but floating point was simpler to start with. Integer has a complication where v32i16/v64i8 aren't legal when the other 512-bit integer types are. llvm-svn: 371325
