BDE Library built with GCC cannot be used with Clang

GCC and Clang are supposedly binary compatible.

However, it seems that the BDE library introduces compiler-dependent types in its public interface, which breaks this compatibility.

Specifically, when building the BDE library with GCC and attempting to consume it using Clang, the following linker error occurs:`
undefined reference to 'BloombergLP::bsls::Review::updateCount(BloombergLP::bsls::Atomic_TypeTraits::Int*)'`

The issue is mainly due to one line in [bdlt_datetime.h](https://github.com/bloomberg/bde/blob/66d3fb1a7cde32d4d99307629bca504da22ab1e4/groups/bdl/bdlt/bdlt_datetime.h#L1136) because it uses `BSLS_REVIEW_INVOKE` in the header. Other usages can be turned off with `BSLS_REVIEW_LEVEL_NONE`.

Is there (still) a reason why there is a Clang specific `BloombergLP::bsls::AtomicOperations_ALL_ALL_ClangIntrinsics` traits class?
The structure of the ifdef-ery in `bsls_atomicoperations.h` looks like Clang also should work with the GCC intrinsics, but the path is not reachable with current Clang versions.
