compiler: bug: trivial unwind-protect return value
Bad test case:
(unwind-protect 42 1 2 3) -> 3 ;; should be 42
* share/txr/stdlib/compiler.tl (compile comp-unwind-protect):
In the case when the protected code compiles to zero code,
because it is a simple variable or constant, the code that
we return must still nominate the that fragment's output
register as its output, and not the output register of the
cleanup forms.
