This provides basic functionality for imported declarations. For subprograms and types some amount of lazy construction is supported (so the definition of a function can proceed the using declaration), but it still doesn't handle declared-but-not-defined functions (since we don't generally emit function declarations). Variable support is really rudimentary at the moment - simply looking up the existing definition with no support for out of order (declaration, imported_module, then definition). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181392 91177308-0d34-0410-b5e6-96231b3b80d8
