[PATCH] D59673: [Driver] Allow setting the DWO name DWARF attribute separately

[Aaron Puchert via Phabricator via cfe-commits]

Ok, here is an idea. We introduce `-split-dwarf-output` in Clang instead of `-fsplit-dwarf-dwo-name-attr`. If given, it overrides the output file name for the Split DWARF file, which we otherwise take from `-split-dwarf-file`. The option is obviously incompatible with `-enable-split-dwarf=single`, so we will disallow that. This should be backwards-compatible, and bring the behavior of `llc` and `clang -cc1` closer together. What do you think?
