* AstGen: LocalVal and LocalPtr use string table indexes for their names. This is more efficient because local variable declarations do need to include the variable names so that semantic analysis can emit a compile error if a declaration is shadowed. So we take advantage of this fact by comparing string table indexes when resolving names. * The arg ZIR instructions are needed for the above reasoning, as well as to emit equivalent AIR instructions for debug info. Now that we have these arg instructions, get rid of the special `Zir.Inst.Ref` range for parameters. ZIR instructions now refer to the arg instructions for parameters. * Move identAsString and strLitAsString from Module.GenZir to AstGen where they belong.

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.
