Update the compiler_builtins crate

[alexcrichton]

This updates to 0.1.13 for compiler_builtins, published to fix a few
issues. The feature changes here are updated because compiler_builtins
no longer enables the c feature by default but we want to do so
through our build still.

Closes#60747
Closes#60782

[cuviper]

Note that bootstrap.py currently doesn't initialize src/llvm-project if you've configured an external LLVM. Are we going to always require that checkout now? Or should there be a way to use an external (possibly precompiled) compiler-rt too?

[alexcrichton]

Hm that's an excellent point @cuviper, thanks for bringing it up! In the interest of landing bug fixes sooner I'm gonna submit that as a separate change and go back to 0.1.14 which only fixes the bugs that are plaguing master right now.

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

1. git checkout update-compiler-builtins(switch to your branch)
2. git fetch upstream master(retrieve the latest master)
3. git rebase upstream/master -p(rebase on top of it)
4. Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
5. git push self update-compiler-builtins --force-with-lease(update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.
