Joe Groff e5b0ffc2df SILGen: Use the original function address as the ID for key paths to import-as-member properties.

If an import-as-member property was used in a key path, we'd try to identify the component by its
foreign-to-native thunk, which isn't normally generated (causing a crash from the missing symbol)
and wouldn't be globally unique even if it were. Fixes rdar://problem/60519829.
