[PATCH] D25929: Add llvm-echo command.

[Rui Ueyama via llvm-commits]

ruiu added a comment.

It should be easy to run our own "echo" instead of system's echo because I think it's doable just by renaming this executable "echo" as opposed to "llvm-echo". I think the build subdirectory has higher precedence in $PATH in the lit tests, so any command that has the same name as a system command overwrites the existing one. If everybody's fine, I can name this echo instead of llvm-echo.

But if we do that, I think this echo command needs more features. I believe some tests pass command line options such as -n to echo.
