I assume not just that but libgomp.c-c++-common/get-mapped-ptr-1.c too?

It both needs the same treatment, and in the get-mapped-ptr-1.c
case there is even UB, while the Fortran version was using c_loc (q)
as the host pointer, in C/C++ it was using q which was value of
uninitialized pointer.

	* testsuite/libgomp.c-c++-common/get-mapped-ptr-1.c (main): Initialize
	q to ddress of an automatic variable.  Use -5 instead of -1 in
	omp_get_mapped_ptr call.  Add test with omp_initial_device.
	* testsuite/libgomp.fortran/get-mapped-ptr-1.f90 (main): Use -5 instead
	of -1 in omp_get_mapped_ptr call.  Add test with omp_initial_device.
	Renumber stop arguments afterwards.
