[PATCH] D25929: Add llvm-echo command.

[Rui Ueyama via llvm-commits]

I'm OK with going with this echo and replace all tests using "echo -n" with printf or something.

But printf is not a solution for the specific problem I'm trying to address. Different printf commands on Windows could tokenize command line arguments differently, so it doesn't matter whether it's printf or echo. The problem is that the Windows command line tokenization rule is weird and inconsistent with command to command.
