[libc++] Remove <experimental/{algorithm,functional}>

[philnik]

Summary

The contents of these files have been implemented for at least two releases, so let's remove them according to our policy (https://libcxx.llvm.org/DesignDocs/ExperimentalFeatures.html#id4).

[philnik]

Try to fix CI

I wonder whether we announced this removal in our release notes... But at least the actual removal should be in the release notes.

795

Mainly curious, but are there not tests that use the experimental headers?

[philnik]

Address comments

There are, I just forgot to remove them.

[philnik]

Remove another test

[Mordante]

LGTM!
