This commits add a --lto-newpm-passes= option that can specify the set of passes that need to be run (similarly to what opt already does). This makes testing easier (e.g. tuning the LTO pipeline), among others.
runLTOPasses() is growing (maybe) too much. I can split in two separate functions, if you like that better.
