I'm looking at this as I start thinking about handling `import`. Syntax is based on llvm's `split-file` tool. The `std::vector` -> `llvm::SmallVector` switch is minor, I'm doing it here because I had to touch everything anyways and I think for tests I'll lean slightly more towards the toolchain's way of doing things versus explorer's.
