* remove the -Ddump-zir thing. that's handled through --verbose-ir * rework Fn to have an is_inline flag without requiring any more memory on the heap per function. * implement a rough first version of dumping typed zir (tzir) which is a lot more helpful for debugging than what we had before. We don't have a way to parse it though. * keep track of whether the inline-ness of a function changes because if it does we have to go update callsites. * add compile error for inline and export used together. inline function calls and comptime function calls are implemented the same way. A block instruction is set up to capture the result, and then a scope is set up that has a flag for is_comptime and some state if the scope is being inlined. when analyzing `ret` instructions, zig looks for inlining state in the scope, and if found, treats `ret` as a `break` instruction instead, with the target block being the one set up at the inline callsite. Follow-up items: * Complete out the debug TZIR dumping code. * Don't redundantly generate ZIR for each inline/comptime function call. Instead we should add a new state enum tag to Fn. * comptime and inlining branch quotas. * Add more test cases.

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.
