The debug mode has been broken pretty much ever since it was shipped because it was possible to enable the debug mode in user code without actually enabling it in the dylib, leading to ODR violations that caused various kinds of failures. This commit makes the debug mode a knob that is configured when building the library and which can't be changed afterwards. This is less flexible for users, however it will actually work as intended and it will allow us, in the future, to add various kinds of checks that do not assume the same ABI as the normal library. Furthermore, this will make the debug mode more robust, which means that vendors might be more tempted to support it properly, which hasn't been the case with the current debug mode. This patch shouldn't break any user code, except folks who are building against a library that doesn't have the debug mode enabled and who try to enable the debug mode in their code. Such users will get a compile-time error explaining that this configuration isn't supported anymore. In the future, we should further increase the granularity of the debug mode checks so that we can cherry-pick which checks to enable, like we do for unspecified behavior randomization.
