Get rid of `std.math.F80Repr`. Instead of trying to match the memory layout of f80, we treat it as a value, same as the other floating point types. The functions `make_f80` and `break_f80` are introduced to compose an f80 value out of its parts, and the inverse operation. stage2 LLVM backend: fix pointer to zero length array tripping LLVM assertion. It now checks for when the element type is a zero-bit type and lowers such thing the same way that pointers to other zero-bit types are lowered. Both stage1 and stage2 LLVM backends are adjusted so that f80 is lowered as x86_fp80 on x86_64 and i386 architectures, and identical to a u80 on others. LLVM constants are lowered in a less hacky way now that #10860 is fixed, by using the expression `(exp << 64) | fraction` using llvm constants. Sema is improved to handle c_longdouble by recursively handling it correctly for whatever the float bit width is. In both stage1 and stage2.

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.
