git_commit commit 2696e4fb9567d23ce065a067e7f4909b310daf50

[libc++] Reduce std::conjunction overhead (#124259)

The old and new implementation of `_And` are very close in terms of
performance according to my testing, but the new implementation can also
be used to implement `conjunction`, which make that ~50% faster.
