Change the semantics of evaluating non-local returns for blocks not on stack

Do evaluate the expression unconditionally, think, this is the standard stack-machine semantics. And only on the actual return, check whether the block is on the stack.

This should be tested in the TestSuite... [TODO!]

Remove optimization for avoiding side-effect-tree execution

It is not worth the code duplication, and while it seems to be correct there, it was most likely broken in TruffleSOM until recently.

Allow additional primitives for system classes

Don't show warnings for primitives that are defined in the VM but not the language.
Gives us a bit more freedom to reimplement the standard library at the VM level.
