* 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.
* testsuite/libgomp.c/pr49898-1.c: New test.
