Add missing VIEW_CONVERT_EXPR case in gimplifier

[Eric Botcazou]

We have a proprietary testcase that causes the gimplifier to choke if 
--RTS=sjlj is passed to the Ada compiler, a regression from 3.x.  The
attached patch simply adds the missing VIEW_CONVERT_EXPR in the fb_none
case with side-effects in the gimplifier, mimicing the generic case:

        case ARRAY_REF:
        case ARRAY_RANGE_REF:
        case REALPART_EXPR:
        case IMAGPART_EXPR:
        case COMPONENT_REF:
        case VIEW_CONVERT_EXPR:
          ret = gimplify_compound_lval (expr_p, pre_p, post_p,
                                        fallback ? fallback : fb_rvalue);
          break;

Tested on i586-suse-linux, applied to mainline as obvious.

	* gimplify.c (gimplify_expr): Treat VIEW_CONVERT_EXPR like other
	lvalues in the fb_none case with side-effects.
