utils.c (can_fold_for_view_convert_p): New predicate.

2008-10-06  Eric Botcazou  <ebotcazou@adacore.com>

* gcc-interface/utils.c (can_fold_for_view_convert_p): New predicate.
(unchecked_convert): Use it to disable problematic folding with
VIEW_CONVERT_EXPR in the general case.  Always disable it for the
special VIEW_CONVERT_EXPR built for integral types and cope with
its addressability issues by preserving the first conversion.
