Historically, data formatters all exist in a global repository (the category map) On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex) This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on The advantages of this are: a) language formatters only get created when they might apply b) formatters for a language are clearly owned by the matching language plugin The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters No formatters are moved as part of this change, so practically speaking this is NFC llvm-svn: 246515
