Add dynamic support for aarch64 LSE atomic ops on linux targets when optimized-compiler-builtins is not enabled. A hook, __enable_rust_lse, is provided for the runtime to enable them if available. A future patch will use this to enable them if available. The resulting asm should exactly match that of LLVM's compiler-rt builtins, though the symbol naming for the support function and global does not.

This repository contains two main crates:
