; A #dbg_declare whose address is a module-scope global rather than an alloca.
; The G_GLOBAL_VALUE is selected to the Workgroup OpVariable, so the storage
; operand resolves and the declare is emitted from inside the function.
;
; This is a synthetic case, clang doesn't seem to emit this.
; clang describes an OpenCL __local or a HIP __shared__ variable with a
; DIGlobalVariable, which takes the DebugGlobalVariable path instead.
