[Patch, Fortran] PR 48700: memory leak with MOVE_ALLOC

[Janus Weil]

Hi all,

here is a simple patch which takes care of fixing a memory leak, which
occurs when calling MOVE_ALLOC with allocatable scalar arguments. We
simply missed to deallocate the second argument 'TO', which is
INTENT(OUT), in case it is already allocated.

The patch was regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
