Fixes all the g++ testcases that use dynamic arrays. It used to be that
when we parsed the declaration, we would call variable_size, which would
expand the SAVE_EXPR we generated for the upper bound. But in
function-at-a-time mode we can't do that; we need to defer it until we
expand the declaration of the declaration itself.
