Matt Weber 2f00b6affd Require type_map::stub callers to supply file information
This change attaches file information (`DIFile` reference and line
number) to struct debug info nodes.

Before:

```
; foo.ll
...
!5 = !DIFile(filename: "<unknown>", directory: "")
...
!16 = !DICompositeType(tag: DW_TAG_structure_type, name: "MyType", scope: !2, file: !5, size: 32, align: 32, elements: !17, templateParams: !19, identifier: "4cb373851db92e732c4cb5651b886dd0")
...
```

After:

```
; foo.ll
...
!3 = !DIFile(filename: "foo.rs", directory: "/home/matt/src/rust98678", checksumkind: CSK_SHA1, checksum: "bcb9f08512c8f3b8181ef4726012bc6807bc9be4")
...
!16 = !DICompositeType(tag: DW_TAG_structure_type, name: "MyType", scope: !2, file: !3, line: 3, size: 32, align: 32, elements: !17, templateParams: !19, identifier: "9e5968c7af39c148acb253912b7f409f")
...
```

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
