Rollup merge of #59380 - philipc:thinlto-variant, r=michaelwoerister
Fix invalid DWARF for enums when using ThinLTO We were setting the same identifier for both the DW_TAG_structure_type and the DW_TAG_variant_part. This becomes a problem when using ThinLTO becauses it uses the identifier as a key for a map of types that is used to delete duplicates based on the ODR, so one of them is deleted as a duplicate, resulting in invalid DWARF. The DW_TAG_variant_part isn't a standalone type, so it doesn't need an identifier. Fix by omitting its identifier. ODR uniquing is [enabled here](https://github.com/rust-lang/rust/blob/f21dee2c6179276321a88a63300dce74ff707e92/src/rustllvm/PassWrapper.cpp#L1101).
