Tobias Burnus 948d461954 OpenMP: Add strictly nested API call check [PR102972] 
The teams construct only permits omp_get_num_teams and omp_get_team_num
as API call in strictly nested regions - check for it.

Additionally, for Fortran, using DECL_NAME does not show the mangled
name, hence, DECL_ASSEMBLER_NAME had to be used to.

Finally, 'target device(ancestor:1)' wrongly rejected non-API calls
as well.

	PR middle-end/102972
gcc/ChangeLog:

	* omp-low.c (omp_runtime_api_call): Use DECL_ASSEMBLER_NAME to get
	internal Fortran name; new permit_num_teams arg to permit
	omp_get_num_teams and omp_get_team_num.
	(scan_omp_1_stmt): Update call to it, add missing call for
	reverse offload, and check for strictly nested API calls in teams.

gcc/testsuite/ChangeLog:

	* c-c++-common/gomp/target-device-ancestor-3.c: Add non-API
	routine test.
	* gfortran.dg/gomp/order-6.f90: Add missing bind(C).
	* c-c++-common/gomp/teams-3.c: New test.
	* gfortran.dg/gomp/teams-3.f90: New test.
	* gfortran.dg/gomp/teams-4.f90: New test.

libgomp/ChangeLog:
	* testsuite/libgomp.c-c++-common/icv-3.c: Nest API calls inside
	parallel construct.
