re PR c++/67522 (OpenMP ICE in type_dependent_expression_p)

	PR c++/67522
	* semantics.c (handle_omp_array_sections_1): Only run
	type_dependent_expression_p on VAR_DECL/PARM_DECLs.
	(finish_omp_clauses) <case OMP_CLAUSE_LINEAR>: Likewise.
	Don't adjust OMP_CLAUSE_LINEAR_STEP if OMP_CLAUSE_DECL
	is not a VAR_DECL/PARM_DECL.

	* g++.dg/gomp/pr67522.C: New test.
