540ef3e010 elf: sort sections by their rank to combine them by segment flags 
Currently this ignores ZigModule, however, I believe we can make it
so that this is done excluding sections/segments emitted by ZigModule
and everything should work out just fine.

f708c5fafc CLI: finish updating module API usage 
Finish the work started in 4c4fb839972f66f55aa44fc0aca5f80b0608c731.
Now the compiler compiles again.

Wire up dependency tree fetching code in the CLI for `zig build`.
Everything is hooked up except for `createDependenciesModule` is not yet
implemented.

0134e5d2a1 codegen: separate getAnonDeclVAddr into lowerAnonDecl and the former 
Implement the stub for Elf.

I believe that separating the concerns, namely, having an interface
function that is responsible for signalling the linker to lower
the anon decl only, and a separate function to obtain the decl's
vaddr is preferable since it allows us to handle codegen errors
in a simpler way.

285970982a Add illumos OS tag 
- Adds `illumos` to the `Target.Os.Tag` enum. A new function,
  `isSolarish` has been added that returns true if the tag is either
  Solaris or Illumos. This matches the naming convention found in Rust's
  `libc` crate[1].
- Add the tag wherever `.solaris` is being checked against.
- Check for the C pre-processor macro `__illumos__` in CMake to set the
  proper target tuple. Illumos distros patch their compilers to have
  this in the "built-in" set (verified with `echo | cc -dM -E -`).

  Alternatively you could check the output of `uname -o`.

Right now, both Solaris and Illumos import from `c/solaris.zig`. In the
future it may be worth putting the shared ABI bits in a base file, and
mixing that in with specific `c/solaris.zig`/`c/illumos.zig` files.
