If the target files contains `//line` directive and it indicates a non-go file, the linter is going to handle it as a go file, which results in failure. The cause of this issue is that the linters (`Analyzer`s) are using `pass.Fset.Position()`. This func returns the adjusted position using `//line` directive. The example project reported in #998 has `//line` directive that indicates other non-go file. According to the description of "Compiler Directives” (https://golang.org/cmd/compile/#hdr-Compiler_Directives), line directives is mainly used for reporting original positions to the generators or something. On linters of golangci-lint, `pass.Fset.Position()` is used just to aggregate file names; we don't have to adjust positions. This changes `Analyzer`s that use `pass.Fset.Position()` to aggregate file names to use `pass.Fset.PositionFor()` with `adjusted == false`. Relates: #998
