e7ee9b15 - [C23] Fix failing assertion on structural equivalence checks (#201650)

[C23] Fix failing assertion on structural equivalence checks (#201650) This assertion was added in 6a22580305d779e2d712900d49578de9a5cb14e8 as a sanity check and it turns out that the assertion was false in two different ways. 1) An enumeration might not have an underlying type in our AST; this happens for a forward declared enumeration without a fixed underlying type. 2) When comparing the members, we could compare a member of enumeration type with a member of a non-integral type like a union or structure. We now account for both cases. Fixes #190227
