* omp-low.c (maybe_lookup_decl_in_outer_ctx): New function.
(build_outer_var_ref): Use maybe_lookup_decl_in_outer_ctx
to find if var will be a global variable even in the nested context.
(omp_copy_decl): Only check for global variable at the end, it might
be overridden in outer contexts.
(scan_sharing_clauses): For global variables don't create a field.
(lower_rec_input_clauses): Do nothing for global shared variables.
Emit a barrier at the end of ILIST if there were any decls in both
firstprivate and lastprivate clauses.
(lower_send_clauses): Do nothing for global variables except for
COPYIN.

around RESULT_DECL for result passed by reference.

DECL_HAS_VALUE_EXPR_P for RESULT_DECLs.

(lower_rec_input_clauses): Don't allocate VLA memory for the second
time or var for passing by reference for
OMP_CLAUSE_LASTPRIVATE_FIRSTPRIVATE clauses. Allow creation of
TREE_ADDRESSABLE variables when passing by reference.
