I can build and test this patch on NetBSD/amd64.

I don't have access right now to a performant FreeBSD, Linux, Android, Windows and FreeBSD hosts to test build and execute tests for this patch on other platforms. Please check.

I was in touch with `libstdc++` developers and the reason why `std::call_once` crashes is still cryptic. A combination of TLS, shared library and pointer to a function passed to `pthread_once`(3) results in a crash. Switch LLDB to the standard LLVM wrapper for `std::cal_once`.

Few months back discussed with @mehdi_amini in the context of LLVM.
