; Make sure we reject GVs without a type.
; Currently the verifier when traversing the graph induced by the debug info
; metadata can reach the GV both from a DICompileUnit and a DIGlobalVariable
; expression, so we emit a diagnostic twice. This is, not ideal, but the
; alternative is that of keeping a map of visited GVs, which has non trivial
; memory usage consequences on large testcases, or when LTO is the mode of
; operation.
