----------------
We do have `BoolFOption` for `-fsomething`/`-fno-something` options.

----------------
I'd pass the library prefix argument as a string, instead of a boolean flag. Makes it easier to tell what's going on without having to annotate it as a comment. 

Also, maybe consider separating "get the list of bitcode files" from "construct aguments for tool X for the given list of bitcode files". Right now `addHIPDeviceLibArgs` does both and has to plumb the `UseMLinkOpt`through multiple function calls. Adding the prefix argument can be done at the `constructLldCommand`/`addClangTargetOptions`.
