MoarVM panic from race return

[DarthGandalf]

The Problem

sub f() {
        race for ^10 {
                return 2 if 5;
        }
}
f();

Expected Behavior

f() should return 2.

If several iterations had the condition succeed, I'd expect any of them to be returned - in case of hyper it would be the first one instead.

Actual Behavior

MoarVM panic: Internal error: Unwound entire stack and missed handler

Hyper also crashes the same way.

Steps to Reproduce

Just run that code. --ll-exception provides no additional details for me.

Environment
