rustc: Link LLVM directly into rustc again

[alexcrichton]

This commit builds on #65501 continue to simplify the build system and
compiler now that we no longer have multiple LLVM backends to ship by
default. Here this switches the compiler back to what it once was long
long ago, which is linking LLVM directly to the compiler rather than
dynamically loading it at runtime. The codegen-backends directory of
the sysroot no longer exists and all relevant support in the build
system is removed. Note that rustc still supports a dynamically loaded
codegen backend as it did previously, it just no longer supports
dynamically loaded codegen backends in its own sysroot.

Additionally as part of this the librustc_codegen_llvm crate now once
again explicitly depends on all of its crates instead of implicitly
loading them through the sysroot. This involved filling out its
Cargo.toml and deleting all the now-unnecessary extern crate
annotations in the header of the crate. (this in turn required adding a
number of imports for names of macros too).

The end results of this change are:

• Rustbuild's build process for the compiler as all the "oh don't forget
  the codegen backend" checks can be easily removed.
• Building rustc_codegen_llvm is much simpler since it's simply
  another compiler crate.
• Managing the dependencies of rustc_codegen_llvm is much simpler since
  it's "just another Cargo.toml to edit"
• The build process should be a smidge faster because there's more
  parallelism in the main rustc build step rather than splitting
  librustc_codegen_llvm out to its own step.
• The compiler is expected to be slightly faster by default because the
  codegen backend does not need to be dynamically loaded.
• Disabling LLVM as part of rustbuild is still supported, supporting
  multiple codegen backends is still supported, and dynamic loading of a
  codegen backend is still supported.

This pretty much looks great to me -- less steps in bootstrap is always an improvement!

[bjorn3]

Why is this now needed?

[alexcrichton]

We didn't check it before? It's presumably only depended on by librustc_codegen_lvm

[bjorn3]

Maybe move this to get_builtin_codegen_backend and rename that function to get_codegen_backend, while renaming this function to get_codegen_backend_for_sess or even inline this function.

[alexcrichton]

I'm not sure I understand? What would the purpose of that movement be?

[bjorn3]

The purpose of that change is that the version which doesn't take a Session as input will accept /path/to/backend.so. I am fine with keeping it the way it is right now.

[bjorn3]

Just to confirm, this one still works? Or do I need to use llvm.enabled instead?

[bjorn3]

It would also be nice if this would automatically pass a feature flag for every item, even unknown ones, so adding a codegen backend is as easy as adding a few crate features, adding optional deps, and changing rustc_interface to recognize the -Zcodegen-backend value for it.

[alexcrichton]

It should be the case that setting this to the empty array should work. I'll leave it to future PRs though to continue to tweak how multiple codegen backends work.

[bjorn3]

Maybe rename to cg_llvm?

[alexcrichton]

Perhaps? It's all internal anyway and can change at any time, I sort of prefer just llvm but feel free to send a PR after this if you feel differently.
