Doug Gregor 9a20ebac5b [Embedded] Emit weak definitions for imported symbols ...

When Embedded Swift emits a symbol that was imported from another
module, ensure that the symbol is emitted as a weak definition. This
way, importing the same module (and using its symbol) into several
different modules doesn't cause duplicate-symbol errors at link time.
Rather, the linker will merge the different symbol definitions. This
makes Embedded Swift libraries work without resorting to
`-mergeable-symbols` or `-emit-empty-object-file`.
