New Revision: 183325

URL: http://llvm.org/viewvc/llvm-project?rev=183325&view=rev
Log:
When the template specialization header is missing, set a valid source location for the template keyword when recovering.

Otherwise ClassTemplateSpecializationDecl::getSourceRange() will mistakenly consider itself as an implicit partial specialization
and lead to a crash.

Fixes rdar://14063074
