fixes #23295

Or use isCaseObj to filter types

[ringabout]

One way or another, we should extend dontInlineConstant to case object variants because of the data structures of object variants stored in the VM.

We can choose either apply noinline to cnst which is a complex constant (array, etc.) or we need to inspect the types or nodes of cnst in order to enforce noinline for object variants.
