[PATCH] D50209: cmake: Explicitely specify benchmark data

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

Some notes:

- I is only for the benchmarks shipping with the test-suite yet. The things in `External` will need some additional changes (they will keep working as is, just won't consistenly have their data in the builddir)
- The copying grows the builddir from ~900MB to 1GB for me. If this is a concern then we could add a mode that creates symlinks when the test-suite is running locally; however I wasn't convinced yet it is worth having two modes just for 100MB savings in the builddir.

  rT test-suite
