When using lit's internal shell, RUN lines like the following accidentally execute an external `diff` instead of lit's internal `diff`: ``` # RUN: program | diff file - ``` Such cases exist now, in `clang/test/Analysis` for example. We are preparing patches to ensure lit's internal `diff` is called in such cases, which will then fail because lit's internal `diff` doesn't recognize `-` as a command-line option. This patch adds support for `-` to mean stdin. Reviewed By: probinson, rnk Differential Revision: https://reviews.llvm.org/D67643
