Having an enum member named Default is quite confusing: Is it distinct from the others? This patch removes that member and instead uses Optional<Reloc> in places where we have a user input that still hasn't been maped to the default value, which is now clear has no be one of the remaining 3 options. llvm-svn: 269988
