"""LLVM libc starlark rules for tests.
libc functions are created though the libc_build_rules.bzl:libc_function.
They come in two flavors:
- the internal one that is scoped into the `__llvm_libc` namespace.
- the libc one that is the regular C function.
When performing tests we make sure to always use the internal version.
