[PATCH] D115433: [CommandLine] Reset option to its default if its Default field is undefined

[David Greene via Phabricator via llvm-commits]

greened added a comment.

What is the motivation for this change?  I can argue for maintaining the current behavior.,  If I pass a `cl::init` to an option and call `ResetAllOptionOccurrences` I would expect that `cl::init` value to be used to reset the option.  There are compiler flows that rely on that behavior.
