// This test uses dlopen to jump ahead in the initializer graph
// The static linkages here should result in initializers being run in the order libbaz, libfoo, libbar
// However, a dlopen of libbar inside libfoo's static initializer means we need to skip ahead and initialize libbar to satisfy that dlopen
// This means that the closure needs to have "initializer-order" on libfoo and not just the top level executable image.
// It also means that dlopen needs to check we have actually initialized libbar instead of just bumping its ref-count.
