Issue Description:

This is currently only relevant to the master-next branch of Swift, which works with the latest version of LLVM. Recent work on LLVM adds support distinguishing runtime-preemptable symbols by marking them as either dso_local or dso_preemptable. Setting those flags correctly probably requires some work in the Swift frontend. Compare with Clang r324535.

I made some related changes in #14572 but that was just enough to get one test to pass.
