[libcxx-commits] [libcxxabi] [libcxxabi] Rename abort_message to __abort_message (PR #108887)

[Louis Dionne via libcxx-commits]

I'm OK with this change, but FWIW it doesn't really matter since this doesn't leak into any public headers. I'm still fine with it just consistency-wise.

The thing we'd really really like to do is

(1) merge libc++abi into libc++ code-wise (to reduce duplication etc)
(2) use `__verbose_abort` directly instead of `__abort_message`

But that requires doing (1), which is some engineering effort.
