[PATCH 13/14] compiler-context-analysis: Split the RCU assertion tests

[Bart Van Assche]

Split test_rcu_assert_variants() in lib/test_context-analysis.c into
test_rcu_assert(), test_rcu_assert_bh() and test_rcu_assert_sched() such
that each RCU assertion variant is tested independently. Add
test_rcu_assert_reader() to test lockdep_assert_in_rcu_reader().
