JVM_IR: unwrap suspend views when generating SAM wrappers

If the super class is in a file that has already been lowered, the base
method has an extra continuation parameter which breaks things.

Also, SAM wrappers around functional objects are tail-call and do not
need continuations ever, so don't even try.
