+ location, because the frontend attached custom data to it. In order for the
+ diagnostic pragma to correctly understand that the diagnostic pop occurs
+ after the function and not before, linemap_location_before_p needs to handle
+ adhoc locations within a macro map, which was broken until fixed by r10-325.
+ Verify that we get it right, both when the brace is a macro token and when it
+ is part of the macro expansion. */
