Closes #134996. The crash about `TypeInfoLValue` is https://godbolt.org/z/73WY31s55. After the patch: ```cpp //test.cpp #include <typeinfo> constexpr const std::type_info* val = &typeid(int); ``` ``` lambda@ubuntu22:~/test$ clang++ -std=c++20 -Xclang -ast-dump -fsyntax-only test.cpp LValue Base=TypeInfoLValue typeid(int), Null=0, Offset=0, HasPath=1, PathLength=0, Path=() ``` ```cpp //DAtest.cpp constexpr int *m = new int(42); ``` ``` lambda@ubuntu22:~/test$ clang++ -std=c++20 -Xclang -ast-dump -fsyntax-only DAtest.cpp LValue Base=DynamicAllocLValue 'int', Null=0, Offset=0, HasPath=1, PathLength=0, Path=() ```
