Mark Hall is implementing
constinitfor MSVC in internal MSVC-PR-301193 and needs to suppress a harmless warning in test code.We disable magic statics in our test suite, and enable the off-by-default warning C4640, to find any places where we're unintentionally using magic statics in product code. Here, this test code is eligible for
constinit, but needs magic statics because its destructor is non-trivial. That's okay, so we can just suppress the warning.
