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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@269988 91177308-0d34-0410-b5e6-96231b3b80d8
