The code would previously assume every function would start at addresses being multiples of 16, this is not true beside some specific cases. Moreover LLVM picks different alignment values depending on whether it's trying to generate dense or fast code. Let's use the minimum guaranteed alignment as base value, computed according to how big the opcodes are. The alignment of function pointers is always 1, a safe value that won't cause any error at runtime. Note that this was already the case before this commit, here we're making this choice explicit. Let the 'alignment' field for TypeInfo of fn types reflect the ABI alignment used by the compiler, make this field behave similarly to the 'alignment' one for pointers.

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.
