BBVectorize: Omit unnecessary entries in PairableInstUsers
This map is queried only for instructions in pairs of pairable instructions; so make sure that only pairs of pairable instructions are added to the map. This gives a 3.5% speedup on the csa.ll test case from PR15222. No functionality change intended. llvm-svn: 174914
