Justin Bogner a16104e6da [Option] Add "Visibility" field and clone the OptTable APIs to use it ... This splits OptTable's "Flags" field into "Flags" and "Visibility", updates the places where we instantiate Option tables, and adds variants of the OptTable APIs that use Visibility mask instead of Include/Exclude flags. We need to do this to clean up a bunch of complexity in the clang driver's option handling - there's a whole slew of flags like CoreOption, NoDriverOption, and FlangOnlyOption there today to try to handle all of the permutations of flags that the various drivers need, but it really doesn't scale well, as can be seen by things like the somewhat recently introduced CLDXCOption. Instead, we'll provide an additive model for visibility that's separate from the other flags. For things like "HelpHidden", which is used as a "subtractive" modifier for option visibility, we leave that in "Flags" and handle it as a special case. Note that we don't actually update the users of the Include/Exclude APIs here or change the flags that exist in clang at all - that will come in a follow up that refactors clang's Options.td to use the increased flexibility this change allows.
