Tim Chevalier 91e44ea056 Be a little more clever about calculating sizes for class types
We could try to calculate the size of a partially-converted class type,
and run into an LLVM error because we were trying to calculate the size
of a named struct whose fields hadn't yet be filled in. The issue can be
dodged by extending simplify_type to convert classes to isomorphic
structural records, just for the purposes of size calculations.

(for real this time) Closes #2718
