Fix C++ __builtin_constant_p

We have two desires for interaction of __builtin_constant_p with
constexpr: 1) it should be a constant-expression even if its operands
are not, and 2) we shouldn't fold it to false prematurely when parsing a
constexpr function (c++/54021). We were having trouble with both of
these, and this patch fixes #1 without breaking #2.
