Make diagnostics slightly more colorful
This is a preliminary commit to add colors to diagnostics (warning and
error messages). The aesthetic changes are:
- 'warning', 'error', and 'fatal' are all colored magenta, red, and
red respectively.
- The warning annotation [-Wsomething] shares the same color.
- Warnings and errors are also bolded (this is consistent with what
other compilers do).
A new flag has been added to control the behavior:
-fdiagnostics-color=(always|auto|never)
This flag is 'auto' by default. However, auto-detection is not
implemented yet, so it effectively it defaults to off.
