Add a script to run a command but ignore its return code. This script

always returns 0. This is useful with the llvm.exp based dejagnu testing
when a test wants to check the error output of tool invocation that
returns non-zero. Since every command is checked with llvm.exp, there needs
to be a way to prevent that checking and this script is it.
