We had some regressions in the ability for _Pragma to disable a warning
(PR preprocessor/69126, PR preprocessor/69543, PR preprocessor/69558).
This patch attempts to add more test coverage for this, for the
various combinations of:
- various warnings:
-Wunused-variable
-Wuninitialized
-Wdeprecated-declarations
- various combinations of location of _Pragma relative to location of
the warning:
- _Pragma is in a macro, warning isn't a macro
- neither is in a macro
- _Pragma isnt't in a macro, warning is in a macro
- in different macros
- both in the same macro
- C vs C++ frontend.
It adds some XFAILs:
- pr69543-1.c for C++ (fixed in the followup patch)
- pr69543-3.c for both C and C++
- pr69543-4.c for both C and C++
- pr69558.c for C++ (moving it from gcc.dg to c-c++-common,
marking it as xfail for C++ for now)
