It's probably worth evaluating on a case by case basis.  Often time there
are ways to use lower level LLVM tools like llvm-mc, yaml2obj, etc so that
we can construct binaries on the fly which are reproducible.  In these
cases we should check in the "meta-inputs" that allow us to reproducibly
construct the test inputs on the fly.

One can easily imagine the repository growing to many tens of gigabytes
just due to test inputs, which is not really scalable.
