PR middle-end/49897
	PR middle-end/49898
	* omp-low.c (use_pointer_for_field): If disallowing copy-in/out
	in nested parallel and outer is a gimple_reg, mark it as addressable
	and set its bit in task_shared_vars bitmap too.

	* testsuite/libgomp.c/pr49897-1.c: New test.
	* testsuite/libgomp.c/pr49897-2.c: New test.
