The code (from T23465.hs)

Closes #23892

Resolves #23829.
The stage violation results in out-of-bound names in splices.
Technically this is an error, but someone might rely on this!?
Internal changes:
- we now track stages for TyVars.
- thLevel (RunSplice _) = 0, instead of panic, as reifyInstances does
in fact rename its argument type, and it can contain variables.

Fixes #22012 by adding the symbols described in
https://github.com/llvm/llvm-project/blob/main/llvm/docs/Atomics.rst#libcalls-atomic.
Ultimately this would be better addressed by #22011, but this is a first
step in the right direction and fixes the immediate symptom.
Note that we dropped the `__arch64_cas16` operations as these provided
by all platforms's compilers. Also, we don't link directly against the
libgcc/compiler-rt definitions but rather provide our own wrappers to
work around broken toolchains (e.g. https://bugs.gentoo.org/868018).
