Summary: Currently when --passes is used, any passes specified via -foo are ignored. Explicitly bail out when that happens. This requires changing some tests. Most were straightforward, but codegenprepare-produced-address-math.ll is tricky. One of its RUNs runs CodeGenPrepare. I tried porting CodeGenPrepare to the NPM, but ended up getting stuck when I needed a TargetMachine. NPM doesn't have support for MachineFunctions yet. So I just deleted that RUN line, since it was mass-added in https://reviews.llvm.org/D54848 and is likely not that useful.
