Fix AtomicHook init-order fiasco under MSVC 2019.
On this platform, constexpr static init sometimes happens after dynamic init =/. When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone. This works even when constexpr static init goes first since all uses of AtomicHook should have static storage duration and be zero-initialized.
