openmp: Handle OMP_MASKED in potential_constant_expression_1 [PR103349]

WHen adding OMP_MASKED, I apparently forgot to handle it in
potential_constant_expression_1, which means we can ICE on it.

2021-11-22  Jakub Jelinek  <jakub@redhat.com>

	PR c++/103349
	* constexpr.c (potential_constant_expression_1): Punt on OMP_MASKED.

	* g++.dg/gomp/masked-1.C: New test.
