some const cleanup: remove unnecessary attributes, add const-hack indications

I learned that we use `FIXME(const-hack)` on top of the "const-hack" label. That seems much better since it marks the right place in the code and moves around with the code. So I went through the PRs with that label and added appropriate FIXMEs in the code. IMO this means we can then remove the label -- Cc ``@rust-lang/wg-const-eval.``

I also noticed some const stability attributes that don't do anything useful, and removed them.
