Deduce "nofree" function attribute.

There are a few things to consider.

1. To use llvm::isFreeCall, I need TargetLibraryInfo(TLI) in AANoFreeFunction. For now, I lift TLI to AANoFreeFunction constructor from AttributorPass::run. Therefore, I changed some interface. I'm not sure this is appropriate. Perhaps it is better that Attributor have TLI as a member.
