My current understanding (after chatting with @arphaman) is that editor 
placeholders isn't a great fit here:

- For non IDE uses of this, it will just be weird to output something like 
`#include <<#framework-name#>/Foo.h>`. Even if we wanted to emit this only for 
IDE use, clang currently has no way to make that distinction (editor 
placeholder related compiler flags only make sense when actually making the 
special token sequence lexable, not when generating it)
- Fixits are (with some known exceptions) meant to be applied to code and 
subsequently allow compilation to succeed, this wouldn't be the case here.
