[Concepts] Fix ConceptSpecializationExpr profiling crash
ConceptSpecializationExprs (CSEs) were being created with nullptr
TemplateArgsAsWritten during TemplateTemplateParmDecl canonicalization,
and we were relying on them during profiling which caused sporadic
crashes in test/CXX/.../temp.arg.template/p3-2a.cpp introduced in
D44352.
Change profiling of CSEs to instead rely on the actual converted
template arguments and concept named.
The file was modifiedclang/lib/AST/StmtProfile.cpp
