llvm-ir containing DW_TAG_variant_part

The attached file (test.ll) contains the LLVM-IR for the following Rust code:

pub enum AB {
    A(i32),
    B(i32),
}

pub fn test(x: AB) -> AB {
    x
}

The following commands reproduce the contents of test.ll as expected:
opt test.ll -S -disable-debug-info-type-map
llvm-as test.ll && opt test.bc -S -disable-debug-info-type-map

The output of the following command is missing the DW_TAG_variant_part and its
children:
opt test.ll -S

The output of the following command is missing the DW_TAG_structure_type:
llvm-as test.ll && opt test.bc -S</pre>
