LLVM arguments accept "noalias", which is nice. We can do type-based alias analysis to set it.

We now tag &mut parameters as noalias, I'm going to close this bug and open more specific issues for other potential uses.

Add aarch64 support to newlib bindings

It's all in the title. I grabbed the definition from  a small test in with a gcc toolchain, I hope it's correct.

There's currently no tests around newlib in the CI. Would it be possible to add them ? If so, how ?
