In preparation for running clang-format on the whole code base, we are also removing mentions of the legacy _LIBCPP_INLINE_VISIBILITY macro in favor of the newer _LIBCPP_HIDE_FROM_ABI. We're still leaving the definition of _LIBCPP_INLINE_VISIBILITY to avoid creating needless breakage in case some older patches are checked-in with mentions of the old macro. After we branch for LLVM 18, we can do another pass to clean up remaining uses of the macro that might have gotten introduced by mistake (if any) and remove the macro itself at the same time. This is just a minor convenience to smooth out the transition as much as possible. See https://discourse.llvm.org/t/rfc-clang-formatting-all-of-libc-once-and-for-all for the clang-format proposal.
