With this change, libFuzzer will ignore any arguments after a sigil argument, but it will preserve these arguments at the end of the command line when launching subprocesses. Using this, its possible to handle positional and single-dash arguments to the program under test by discarding everything up to -ignore_remaining_args=1 in LLVMFuzzerInitialize. llvm-svn: 308069
