Fortran/OpenMP: Accept implicit-save DATA vars for threadprivate [PR99514]

gcc/fortran/ChangeLog:

	PR fortran/99514
	* resolve.c (resolve_symbol): Accept vars which are in DATA
	and hence (either) implicit SAVE (or in common).

gcc/testsuite/ChangeLog:

	PR fortran/99514
	* gfortran.dg/gomp/threadprivate-1.f90: New test.
