[PATCH] testsuite: Add test for already-fixed issue with _Pragma expansion [PR90400]

[Lewis Hyatt]

Hello-

This is adding a testcase for a PR that was already incidentally fixed. OK
to commit please? Thanks...

The PR was fixed by r12-5454. Since the fix was somewhat incidental,
although related, add a testcase from PR90400 too before closing it out.

gcc/testsuite/ChangeLog:

	PR preprocessor/90400
	* c-c++-common/cpp/pr90400.c: New test.

OK, thanks.  (Not really my area, but someone would probably have
objected by now if they were going to.)
