`_LIBCPP_ENABLE_ASSERTIONS` is deprecated, and will be removed. [See (from libc++ __config in main)](https://github.com/llvm/llvm-project/blob/b57df9fe9a1a230f277d671bfa0884bbda9fc1c5/libcxx/include/__config#L205-L209):
> TODO(hardening): remove this in LLVM 19.
> This is for backward compatibility -- make enabling `_LIBCPP_ENABLE_ASSERTIONS` (which predates hardening modes)
> equivalent to setting the safe mode.
> ifdef _LIBCPP_ENABLE_ASSERTIONS
> warning "_LIBCPP_ENABLE_ASSERTIONS is deprecated, please use _LIBCPP_ENABLE_SAFE_MODE instead."
From LLVM 17, `_LIBCPP_ENABLE_DEBUG_MODE` can be used instead.
See https://libcxx.llvm.org/Hardening.html.
Related to #28476.

It was deprecated in LLVM 15, turned into a compile-time error in LLVM 16:
```bash
In file included from /usr/lib/llvm-16/bin/../include/c++/v1/cassert:19:
/usr/lib/llvm-16/bin/../include/c++/v1/__assert:22:5: error: "Defining _LIBCPP_DEBUG is not supported anymore.
Please use _LIBCPP_ENABLE_DEBUG_MODE instead."
^
1 error generated.
```
and has been removed entirely in LLVM 17 (main),
https://github.com/llvm/llvm-project/commit/ff573a42cd1f1d05508f165dc3e645a0ec17edb5.
Building libc++ in debug mode, will also automatically set
`_LIBCPP_ENABLE_DEBUG_MODE` (the new define), so adding it to depends
doesn't seem useful, and would just result in redefinition errors.
I'm wondering if as a followup, we could enable a DEBUG build of libc++
in our MSAN CI job?
Somewhat related to https://github.com/google/oss-fuzz/pull/9828, where
it looks like we'll have to sort out getting a DEBUG build of LLVM.

This improves support for LTO by using gcc wrappers for ar, nm, ranlib,
that correctly setup plugin arguments for LTO.
Other HOSTS are using clang.

Linux and mingw enable libstdc++ debugging for extra runtime checks. OSX
doesn't play nice, so don't enable it there.
