The presence of the source_location header does not guarantee the availablility of std::source_location. For instance, if using clang 11 with a modern libstdc++, the source_location header is available, but std::source_location is not available as it would require __builtin_source_location, which clang does not implement. Consequently, we need to explicitly check the feature test macro instead, and only use std::(experimental::)source_location when it is defined.
