PR c++/88337 - P1327R1: Allow polymorphic typeid in constexpr.
Part of P1327R1 is to allow typeid with an operand of polymorphic type in
constexpr. I found that we pretty much support it already, the only tweak
was to allow TYPEID_EXPR (only created in a template) in constexpr in C++20.
* constexpr.c (potential_constant_expression_1): Allow a typeid
expression whose operand is of polymorphic type in constexpr in
C++20.
* rtti.c (build_typeid): Remove obsolete FIXME comment.
* g++.dg/cpp2a/constexpr-typeid1.C: New test.
* g++.dg/cpp2a/constexpr-typeid2.C: New test.
* g++.dg/cpp2a/constexpr-typeid3.C: New test.
* g++.dg/cpp2a/constexpr-typeid4.C: New test.
