Imagine that we run this without the header search and VFS pruning optimizations - the command line will likely refer to unused project-specific source/build directories. Even with those optimizations on, I'm not convinced we have great guarantees regarding the sysroot-only nature of the command line. I would like to see stronger guarantee. One way of doing this is going through the `*Options` classes that contribute to `CompilerInvocation` and adding an API that allows for iteration through all input/output paths. We could use it to check the prefixes of all paths exhaustively (in addition to the logic you already implemented).
