Add test coverage for _Pragma (PR preprocessor 69126, 69543, 69558)

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++

S/390: Adjust movstr-1.c testcase to work with the z13 stpcpy implementation.

* gcc.target/s390/md/movstr-1.c: Allow also the z13 strings
instruction pattern name to prevent the testcase from failing with
-march=z13.

S/390: z13 inline stpcpy implementation.

A handwritten loop for stpcpy using the new z13 vector instructions
appears to be much faster than the millicoded instruction.  However,
the implementation is much longer and therefore will only be enabled
when optimization for speed.

* gcc.target/s390/md/movstr-2.c: New test.
