compiler: for: bugfix: dangling label reference.
An infinite for loop in which the test is explicitly given as nil
rather than omitted fails to compile. A minimal repro test
case for this is (compile-toplevel '(for () (nil) ()))).
Spotted this while reading the compiler code.
* share/txr/stdlib/compiler.tl (compiler comp-for): Test the
test-p variable, not test, to determine whether or not to
generate the loop skip label.
