Subject: [PATCH] openmp: Fix handling of target constructs in static member
functions [PR106829]
Just calling current_nonlambda_class_type in static member functions returns
non-NULL, but something that isn't *this and if unlucky can match part of the
IL and can be added to target clauses.
if (DECL_NONSTATIC_MEMBER_P (decl)
&& current_class_ptr)
is a guard used elsewhere (in check_accessibility_of_qualified_id).

PR c++/106829
* semantics.cc (finish_omp_target_clauses): If current_function_decl
isn't a nonstatic member function, don't set data.current_object to
non-NULL.
* g++.dg/gomp/pr106829.C: New test.
