This crash is basically caused by calling `ASTContext::getRawCommentForDeclNoCacheImp` with its input arguments `RepresentativeLocForDecl` and `CommentsInTheFile` refering to different files. A reduced reproducer is provided in this patch. After the source locations for instantiations of funtion template are corrected in the commit 256a0b298c68b89688b80350b034daf2f7785b67, the variable `CommitsInThisFile` in the function `ASTContext::attachCommentsToJustParsedDecls` would refer to the source file rather than the header file for implicit function template instantiation. Therefore, in the first loop in `ASTContext::attachCommentsToJustParsedDecls`, `D` should also be adjusted for relevant scenarios like the second loop. Fixes #67979 Fixes #68524 Fixes #70550 (cherry picked from commit 5f4ee5a2dfa97fe32ee62d1d67aa1413d5a059e6)
