I don't necessarily think this must be a hard and fast rule.
Are there instances (aside from inlining) that could take
advantage of optimiziation before scalarization?
I've suggested before that it may well be useful to have cases
in which language-specific nodes may survive into SIMPLE. We'd
treat them as black boxes during optimization and call back
into the front end to lower them.
