When we want a runtime pointer to a zero-bit value we use an undef pointer, but what if we want a runtime pointer to a comptime-only value? Normally, if `T` is a comptime-only type such as `*const comptime_int`, then `*const T` would also be a comptime-only type, so anything referencing a comptime-only value is usually also comptime-only, and therefore not emitted to the executable. However, what if instead we have a `*const anyopaque` pointing to a comptime-only value? Certainly, `*const anyopaque` is a runtime type, and so we need some runtime value to store, even when it happens to be pointing to a comptime-only value. In this case we want to do the same thing as we do when pointing to a zero-bit value, so we use `hasRuntimeBits` to handle both cases instead of ignoring comptime. Closes #12025

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
