Add a variant of the `validate_struct_init` ZIR instruction: `validate_struct_init_comptime` which is the same thing except it indicates a comptime scope. Sema code for this instruction now handles default struct field values and detects when the struct initialization resulted in a comptime value, replacing the already-emitted AIR instructions to store each individual field with a single `store` instruction with a comptime struct value as the operand. In the case of a comptime scope, there is a simpler path that only evals the implicit store instructions for default field values, avoiding the mechanism for detecting comptime values. This regressed one test case for the wasm backend, but it's just hitting a different prong of `emitConstant` which currently has "TODO" in there, so I think it's fine.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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.
