CodeGen: fix runtime function dll storage
Properly attribute DLL storage to runtime functions. When generating the runtime function, scan for an existing declaration which may provide an explicit declaration (local storage) or a DLL import or export storage from the user. Honour that if available. Otherwise, if building with a local visibility of the public or standard namespaces (-flto-visibility-public-std), give the symbols local storage (it indicates a /MT[d] link, so static runtime). Otherwise, assume that the link is dynamic, and give the runtime function dllimport storage. This allows for implementations to get the correct storage as long as they are properly declared, the user to override the import storage, and in case no explicit storage is given, use of the import storage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@289776 91177308-0d34-0410-b5e6-96231b3b80d8
