test case

Note that MetadataLoader also swaps these operands, so the bug stays hidden in
a round-trip between Assembly and Bitcode.
Steps to reproduce this bug:

$ cat test.ll
; ModuleID = 'test.ll'
source_filename = "test.ll"

!named = !{!0, !1, !2}

!0 = !DIFile(filename: "path/to/file", directory: "/path/to/dir")
!1 = !DICompositeType(tag: DW_TAG_structure_type, name: "Object")
!2 = !DIObjCProperty(name: "foo", file: !0, line: 7, setter: "setFoo", getter:
"getFoo", attributes: 7, type: !1)

$ opt -S test.ll | diff test.ll -
8c8
< !2 = !DIObjCProperty(name: "foo", file: !0, line: 7, setter: "setFoo",
getter: "getFoo", attributes: 7, type: !1)
---
> !2 = !DIObjCProperty(name: "foo", file: !0, line: 7, setter: "getFoo", getter: "setFoo", attributes: 7, type: !1)
