 ; ASM: .byte   32                      # Attributes: VARIABLE, EXTERNAL
+; ASM-NEXT: .asciz  "ns::global_namespace_variable"       # External Name
+; ASM: .byte   32                      # Attributes: VARIABLE, EXTERNAL
 ; ASM-NEXT: .asciz  "global_variable"       # External Name
----------------
Previously, this was

```
; ASM: .byte   32                      # Attributes: VARIABLE, EXTERNAL
; ASM-NEXT: .asciz  "global_variable"       # External Name
...more lines...
; ASM: .byte   32                      # Attributes: VARIABLE, EXTERNAL
; ASM-NEXT: .asciz  "ns::global_namespace_variable"       # External Name
```

but the reordering resulted in there being another `.byte   32` (a very fragile check line!) before `global_variable`.

-; CHECK:   DW_TAG_subprogram
+; CHECK:   [[GLOBAL_F7:0x[0-9a-f]+]]: DW_TAG_subprogram
+; CHECK:     DW_AT_linkage_name
----------------
Similarly here--`f7` used to be at the end of the list below, and was just ignored, but now it appears in the middle
