[ADT] Add C++20-style llvm::identity_cxx20 (#164143)
Currently, our llvm::identity<T> is not quite like std::identity from
C++20. Ours is a template struct while std::identity is a
non-template struct with templatized operator(). This difference
means that we cannot mechanically replace llvm::identity with
std::identity when we switch to C++20 in the future.
This patch implements llvm::identity_cxx20, which behaves exactly like
std::identity.
Once this patch lands, I'm planning to migrate users of llvm::identity
to the new style. There aren't that many:
- 4 instances of SparseSet<...>
- 3 instances of SparseMultiSet<...>
- about 50 instances of IndexedMap<...>
