    Adding a new 'type category disable *' feature that disables all categories - This is intended as a quick kill switch for data formatters for cases where the user wants as little extra processing as possible to be done on their target, or to override major data formatters bug, should they occur
    
    llvm-svn: 156044
```

And searching the repo for `gnu-libstdc++`, you'll see that the libcxx and lisbtdcpp formatters were written in python and were added to separate categories. Not 100% why they got combined back into the same category. Presumably the idea was that you never want to have both categories enabled anyway, so if a `cplusplus` category can just turn on/off the STL formatters for you that'd be more intuitive.
