Run `function-import` pass in a similar way that it runs in a ThinLTO distributed backend compile and checks that function alias is imported as a definition. More accurately, the function alias [is](0c98776159/llvm/lib/Transforms/IPO/FunctionImport.cpp (L1912)) a [clone](0c98776159/llvm/lib/Transforms/IPO/FunctionImport.cpp (L1782)) of the aliasee function.
