MSVC still does this, but we don't implement this weird behavior. Did
you assume we do from the comment? Then I'll clarify it.

I've often seen this done in LLVM when normal formatting overshoots by
one char. clang-format most likely puts the enum value in the next line.

That's because this patch is Sema-only, and the dllimport function is
still getting linkonce_odr linkage instead of available_externally.
I can try to split out the relevant IRGen changes and tests and put them
up for review sooner.
