* AstGen: emit decl lookup ZIR instructions rather than directly looking up decls in AstGen. This is necessary because we want to reuse the same immutable ZIR code for multiple generic instantiations (and comptime function calls). * AstGen: fix using members_len instead of fields_len for struct decls. * structs: the struct_decl ZIR instruction is now also a block. This is so that the type expressions, default field value expressions, and alignment expressions can be evaluated in a scope that contains the decls from the struct namespace itself. * Add "std" and "builtin" packages to the builtin package. * Don't try to build glibc, musl, or mingw-w64 when using `-ofmt=c`. * builtin.zig is generated without `usingnamespace`. * builtin.zig takes advantage of `std.zig.fmtId` for CPU features. * A first pass at implementing `usingnamespace`. It's problematic and should either be deleted, or polished, before merging this branch. * Sema: allow explicitly specifying the namespace in which to look up Decls. This is used by `struct_decl` in order to put the decls from the struct namespace itself in scope when evaluating the type expressions, default value expressions, and alignment expressions. * Module: fix `analyzeNamespace` assuming that it is the top-level root declaration node. * Sema: implement comptime and runtime cmp operator. * Sema: implement peer type resolution for enums and enum literals. * Pull in the changes from master branch: 262e09c482d98a78531c049a18b7f24146fe157f. * ZIR: complete out simple_ptr_type debug printing

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.
