Trevor Gross 7222fa6f34 Work around out-of-tree testing with a shim crate
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.

compiler-builtins and libm

This repository contains two main crates:

  • compiler-builtins: symbols that the compiler expects to be available at link time
  • libm: a Rust implementation of C math libraries, used to provide implementations in core.

More details are at compiler-builtins/README.md and libm/README.md.
