Put target deduced from executable name at the start of argument list When clang is called as 'target-clang', put deduced target option at the start of argument list so that option '--target=' specified in command line could override it. This change fixes PR34671. llvm-svn: 313760

clang: Make tests using symlinks more consistent. Instead of checking if each symlink exists before removing it, remove the whole temp dir housing the symlinks before recreating it. This is a bit shorter, conceptually simpler (in that the first and consecutive test runs have more similar behavior), it's what we're already doing in almost all places where we do it, and it works if the symlink exists but is a dead link (e.g. when it points into the build dir but the build dir is renamed). No intended behavior change.
