        * calls.c (combine_pending_stack_adjustment_and_call): Return the
        adjustment; don't do the stack adjust.
        (expand_call): Call compute_argument_block_size right before
        allocating the block; update comment; don't do alignment sanity
        checking for sibling call; use args_size instead of
        unadjusted_args_size before args_size is adjusted.  Use
        combine_pending_stack_adjustment_and_call to compute stack adjust
        for must_preallocate case.

        * expr.c (push_block): Remove shadow `temp' in inner scope.
