Infer the return type by finding the common type across all cases.
Types that derive from CastableBase will automatically infer to
the common base class.

Use `static constexpr bool` instead of `std::integral_constant` for `IsTypeOrDerived`. This is often cleaner to use.
Add `IsCastable`, a helper for determining if all the template types derive from `CastableBase`.
Add `CastableCommonBase`, some template magic for determinine the most derived, common base type for all castable types.

* VarForDynamicIndex no longer depends on ForLoopToLoop
* Both can cope with hoisting from "else if"
* More unit tests were added in the interim
Delete PromoteSideEffectsToDecl for now. This may be brought back to

This significantly simplifies the calling code from Dawn.
It does require moving the SingleEntryPoint transform above the
renamer, since we need to call SEP with the original name. That is
probably also an optimization, since we do the subsequent transforms
