runtime/Safepoint/AssertSafepointCheckConsistency[1-4] tests just call a native code, which was placed into whitebox. it's better to use gtest framework for such tests, so wrapper runtime/Safepoint/AssertSafepointCheckConsistency*.java files and WhiteBox::assertMatchingSafepointCall method should be removed, the code of assertMatchingSafepointCall moved to gtest tests where TEST_VM_ASSERT_MSG is used to check the assert messages.
