1. In a struct field redefinition, don't mark the struct erroneous.  The
   field is erroneous, but the struct is otherwise well formed.
2. Don't emit diagnostics about functions that are known to be broken already.

Either fix is sufficient to silence the second diagnostic in the example,
but the combination is better :)

turns on -Wformat but not the extra-args warnings.

1. All all variants of -Wformat*, make them imply -Wformat.  GCC warns 
   if you use -Wformatfoo without -Wformat.  We just make one imply the 
   other.
2. Make -Wformat-nonliteral default to off, like gcc.  It is an incredible
   nuisance.
3. Accept but currently ignore -Wformat-extra-args.

the PCH file) and about missing macro definitions (they'll be
automatically pulled from the PCH file anyway).

We're missing some checking to make sure that new macro definitions
won't have any impact on the PCH file itself (e.g., #define'ing an
identifier that the PCH file used).
