  [clang] Fix a UsingTemplate regression after 3e78fa860235431323aaf08c8fa922d75a7cfffa

TemplateName::getAsTemplateDecl() returns the underlying TemplateDecl
for a UsingTemplate kind template name. We should respect that in the
Profile method otherwise we might desugar the template name unexpectedly
(e.g. for template argument deduction with deduciton guides).
