89cfeeb0 - [clang] fix structural comparison for dependent class member pointer (#133343)

[clang] fix structural comparison for dependent class member pointer (#133343) Fixes a regression introduced in https://github.com/llvm/llvm-project/pull/130537 and reported here https://github.com/llvm/llvm-project/issues/133144 This fixes a crash in ASTStructuralEquivalence where the non-null precondition for IsStructurallyEquivalent would be violated, when comparing member pointers with a dependent class. This also drive-by fixes the ast node traverser for member pointers so it doesn't traverse into the qualifier in case it's not a type, or the class declaration in case it would be equivalent to what the qualifier refers. This avoids printing of `<<<NULL>>>` on the text node dumper, which is redundant. No release notes since the regression was never released. Fixes https://github.com/llvm/llvm-project/issues/133144
