Out-of-tree testing is broken with the most recent update from rust-lang/rust because it makes `compiler-builtins` depend on `core` by path, which isn't usually available. In order to enable testing outside of rust-lang/rust, add a new crate `builtins-shim` that uses the same source as `compiler-builtins` but drops the `core` dependency. This has replaced `compiler-builtins` as the workspace member and entrypoint for tests.

This repository contains two main crates:
compiler-builtins: symbols that the compiler expects to be available at link timelibm: a Rust implementation of C math libraries, used to provide implementations incore.
