re PR middle-end/32362 (ICE: in lookup_decl_in_outer_ctx, at omp-low.c:1508)

	PR middle-end/32362
	* omp-low.c (lookup_decl_in_outer_ctx): Don't ICE if t is NULL,
	but decl is a global var, instead return decl.
	* gimplify.c (gimplify_adjust_omp_clauses_1): Add shared clauses
	even for is_global_var decls, if they are private in some outer
	context.

	* testsuite/libgomp.c/pr32362-1.c: New test.
	* testsuite/libgomp.c/pr32362-2.c: New test.
	* testsuite/libgomp.c/pr32362-3.c: New test.
