include guards don't show up as macro definitions in every translation
unit that imports a module. Macro definitions can, however, be
exported with the intentionally-ugly #__export_macro__
directive. Implement this feature by not even bothering to serialize
non-exported macros to a module, because clients of that module need
not (should not) know that these macros even exist.

The initial incentive was to fix a crash when PCH chaining categories
to an interface, but the fix was done in the "modules way" that I hear
is popular with the kids these days.

Each module stores the local chain of categories and we combine them
when the interface is loaded. We also warn if non-dependent modules
introduce duplicate named categories.

(unsurprisingly) caret diagnostics. This is designed to bring some
organization to the monstrous EmitCaretDiagnostic function, and allow
factoring it more easily and with less mindless parameter passing.

Currently this just lifts the existing function into a method, and
splits off the obviously invariant arguments to be class members. No
functionality is changed, and there are still lots of warts to let
existing code continue functioning as-is. Definitely WIP, more cleanups
to follow.

of the function in question when applicable (that is, not for blocks).
Patch by Joerg Sonnenberger with some stylistic tweaks by me.

When discussing this weth Joerg, streaming the decl directly into the
diagnostic didn't work because we have a pointer-to-const, and the
overload doesn't accept such. In order to make my style tweaks to the
patch, I first changed the overload to accept a pointer-to-const, and
then changed the diagnostic printing layer to also use
a pointer-to-const, cleaning up a gross line of code along the way.

Change err_pp_file_not_found back to an Error; when it's a Warning, we suppress it in system headers.  And it is not a good idea to suppress it in system headers.  (This was originally changed in r134996 to implement -MG.)
