<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Younan Zhang (zyn0217) <details> <summary>Changes</summary> This seems to be low-hanging fruit: We could remove all calls to `Context.getCanonicalTemplateArgument()` and gain a better diagnostic/AST. The non-canonical template arguments shouldn't make a difference when synthesizing a CTAD guide, so this is intended to be an NFC.
