re PR fortran/82568 ([6/7/8] ICE with do-loop inside BLOCK inside omp) 

	PR fortran/82568
	* gfortran.h (gfc_resolve_do_iterator): Add a bool arg.
	(gfc_resolve_omp_local_vars): New declaration.
	* openmp.c (omp_current_ctx): Make static.
	(gfc_resolve_omp_parallel_blocks): Handle EXEC_OMP_TASKLOOP
	and EXEC_OMP_TASKLOOP_SIMD.
	(gfc_resolve_do_iterator): Add ADD_CLAUSE argument, if false,
	don't actually add any clause.  Move omp_current_ctx test
	earlier.
	(handle_local_var, gfc_resolve_omp_local_vars): New functions.
	* resolve.c (gfc_resolve_code): Call gfc_resolve_omp_parallel_blocks
	instead of just gfc_resolve_omp_do_blocks for EXEC_OMP_TASKLOOP
	and EXEC_OMP_TASKLOOP_SIMD.
	(gfc_resolve_code): Adjust gfc_resolve_do_iterator caller.
	(resolve_codes): Call gfc_resolve_omp_local_vars.

	* gfortran.dg/gomp/pr82568.f90: New test.
