See the recent thread here: http://lists.llvm.org/pipermail/cfe-dev/2018-July/058494.html
This patch adds the flag -fno-c++-static-destructors, which disables registration of exit-time destructors of static or thread storage duration variables. This patch also adds [[clang::no_destroy]] and [[clang::always_destroy]] attributes for disabling dtors in -fc++-static-destructors mode, and enabling dtors in -fno-c++-static-destructors mode, respectively. This patch was based on @bruno's https://reviews.llvm.org/D22474.

Thanks for taking a look!

This is only valid for static variables, right? It's probably better to document the function name that way, e.g. isStaticWithNoDestroy.
