[PATCH] D79588: [llvm][Support] Use std::atomic for llvm::call_once

[Brad Smith via Phabricator via llvm-commits]

brad added a comment.

OpenBSD 6.7 is just wrapping up and will be released in a few days. We have switched to Clang for our PowerPC system compiler and thus libc++. It should be Ok to remove OpenBSD from that bit of code.

The original issue as far as I remember is that because we don't have TLS support it was exposing another code path that could sometimes have deadlocks.
