This fixes a long time issue with `lambda`. The `lambda` is a bit
overloaded in OpenGOAL: it's used in the implementation of `let`, and
also to define local anonymous functions.
```
(defmacro let (bindings &rest body)
`((lambda :inline #t ,(apply first bindings) ,@body)
,@(apply second bindings)))
```
```
(defmacro defun (name bindings &rest body)
(let ((docstring ""))
(when (and (> (length body) 1) (string? (first body)))
(set! docstring (first body))
(set! body (cdr body)))
`(define ,name ,docstring (lambda :name ,name ,bindings ,@body))))
```
In the first case of a `let`, a `return` from inside the `let` should
return from the functioning containing the `let`, not the scope of the
`lambda`. In the second case, we should return from the lambda. The way
we told the different between these cases was if the `lambda` was used
"immeidately", in the head of an expression (like it would be for the
`let` macro). But, this falsely triggers when an anonymous function is
used immediately: eg
```
((lambda () (return #f)))
```
should generate and call a real x86 function that returns immediately.
This should fix some death/mission failed stuff in jak 2.
