        <pre>We're failing to instantiate the initializer for a variable template
specialization if its type has internal linkage:

<stdin>:1:24: warning: variable 'var<<anonymous namespace>::S>' has internal
linkage but is not defined [-Wundefined-internal]
template<typename T> T var; namespace { struct S {} s = var<S>; }
                       ^
<stdin>:1:57: note: used here
template<typename T> T var; namespace { struct S {} s = var<S>; }
                                                        ^

The warning is sort of right: if we emit IR for 's', we emit it as 'external
global'.</pre>
