[PATCH] D30668: Add llvm::sys::fs::real_path

[Zachary Turner via Phabricator via llvm-commits]

zturner added a comment.

Makes tilde expansion opt-in, and adds a test for . and .. collapsing.  `shell_expand` does nothing currently on Windows, but we could make it expand environment variables in theory.
