[fullcodegen] Fix assert for operand stack depth tracking. This fixes a corner case that triggered an assert in full-codegens operand stack depth tracking. We stop pushing operands if we overflow the C-stack while iterating the AST. This makes the tracking go out of sync before we fully returned from the tree traversal, at which point the thrown RangeError will abort compilation.
