Saleem Abdulrasool 43b2b596fe ClangImporter: import SwiftShims properly for static linking ...

When building against the static standard library, we should define
`SWIFT_STATIC_STDLIB` to indicate to the shims that the declarations
should be giving hidden visibility and default DLL storage. This is
required to ensure that these symbols are known to be `dso_local` when
compiling to avoid an unnecessary look up through the PLT/GOT or the
indirection through the synthesized `__imp_` symbol and the IAT. This
corrects a number of incorrect code generation cases on Windows with the
static standard library.
