refactor(tvix/eval): Compile OpAssert using conditional jumps r/5082
In order to behave nicely with tryEval, asserts need to leave the instruction pointer in a reasonable place even if they fail - whereas with the previous implementation catching a failed assert would still end up running the op for the *body* of the assert. With this change, we compile asserts much more like an `if` expression with conditional jumps rather than having an OpAssert op.
