[libcxx-commits] [libcxx] [libc++][NFC] Fix include guards in __concepts/ (PR #229398)

[Lorcan Purcell via libcxx-commits]

https://github.com/Lorcan7274 created https://github.com/llvm/llvm-project/pull/229398

Rename the include guards in `__concepts/primary_template.h` and `__concepts/referenceable.h` to match their file paths, like the other headers in `__concepts/`.

Both headers were moved from `__type_traits/` (in #197646 and #199821 respectively) but kept their old guards, `_LIBCPP___TYPE_TRAITS_IS_PRIMARY_TEMPLATE_H` and `_LIBCPP___TYPE_TRAITS_IS_REFERENCEABLE_H`.

Fixes #229284

Subject: [PATCH] [libc++][NFC] Fix include guards in __concepts/

__concepts/primary_template.h was moved from
__type_traits/is_primary_template.h in 597e4ac7fbdd (#197646) and
__concepts/referenceable.h from __type_traits/is_referenceable.h in
0d6aac78ad96 (#199821). Both kept the include guards of the headers they
were moved from. Rename them to match their current paths, as every other
header in __concepts/ does.

Fixes #229284
