Make scalar() propagate lvalueness

As mentioned in ticket #24346, scalar() should not change lvalueness.
The fact that it did was a side effect of the implementation and a
bug.  foo(scalar substr(....)) should pass a substr lvalue to foo just
as it would without scalar() or with a $ prototype (which is meant to
be equivalent to scalar()).

This also makes it possible to force scalar context in list assignment
to lvalue subroutines, as in (foo(), scalar bar()) = @list.
