- Added missing ifdef guard in PointerIntEnum header
- Consistent naming convention for ifdef guards
- Consistent 'end namespace swift'
- Consistent single EOL at end of header files
Start threading all keyword (and contextual keyword) printing through
printName, and add a new PrintNameContext for keywords. For now we just
pass this through without changing behaviour.
Also add an operator<< for printing from the tok:: kind for keywords,
which makes it much more convenient for performing the required
callbacks.
