258fc7f5 - [Clang] Fix -ast-dump-decl-types crashes on concepts (#108142)

[Clang] Fix -ast-dump-decl-types crashes on concepts (#108142) Resolve #94928 This PR adds `if (TD->getTemplateDecl())` to prevent `InnerD` becoming `nullptr`, suggested by @firstmoonlight. I also add `-ast-dump-decl-types` option and declare type `CHECK` to the testcase `clang/test/AST/ast-dump-concepts.cpp`. --------- Co-authored-by: Aaron Ballman <aaron@aaronballman.com>
