testsuite: Move misplaced gcc.c-torture/pr92372.c test [PR92372]

This test got committed into a spot where nothing actually tests it.
As there is no main, I assume it was meant to be gcc.c-torture/compile/
test and the test PASSes after moving there (both x86_64-linux and
i686-linux).  Though, it passed before the PR92372 fixes too.
