The test relied on logic that was reverted with change
915f68de

.

LookupScopePrivate::findSpecialization() gets a "TemplateNameIdTable
&specializations" with a non-deterministic order. Without the extra
logic, the very first entry will be chosen as the found specialization.

The non-deterministic order comes from the TemplateNameId::Compare,
which calls std::lexicographical_compare() with the template arguments,
which are FullySpecifiedTypes. The result of
FullySpecifiedType::operator<() might depend on a pointer comparison.
