Auto merge of #104342 - mweber15:add_file_location_to_more_types, r=wesleywiser
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") ... ``` Fixes #98678 r? `@wesleywiser`
