* fix handling of `ah`, `bh`, `ch`, and `dh` registers (which are actually used as aliases to `dil`, etc. registers). Currenly, we treat them as aliases only meaning when we encounter `ah` we make sure to set the REX.W to promote the instruction to 64bits and use `dil` register instead - otherwise we might have mismatch between registers used in different parts of the codegen. In the future, we can and should use `ah`, etc. as upper 8bit halves of 16bit registers `ax`, etc. * fix bug in `airCmp` where `.cmp` MIR instruction shouldn't force type `Bool` but let the type of the original type propagate downwards - we need this to make an informed choice of the target register size and hence choose the right encoding down the line. * implement lowering of 1-byte and 2-byte values to stack and add matching stage2 tests for x86_64 codegen

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.
