Introduce `Module.ensureFuncBodyAnalyzed` and corresponding `Sema` function. This mirrors `ensureDeclAnalyzed` except also waits until the function body has been semantically analyzed, meaning that inferred error sets will have been populated. Resolving error sets can now emit a "unable to resolve inferred error set" error instead of producing an incorrect error set type. Resolving error sets now calls `ensureFuncBodyAnalyzed`. Closes #11046. `coerceInMemoryAllowedErrorSets` now does a lot more work to avoid resolving an inferred error set if possible. Same with `wrapErrorUnionSet`. Inferred error set types no longer check the `func` field to determine if they are equal. That was incorrect because an inline or comptime function call produces a unique error set which has the same `*Module.Fn` value for this field. Instead we use the `*Module.Fn.InferredErrorSet` pointers to test equality of inferred error sets.

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.
