bogus calls cleanup

[Richard Henderson]

        * calls.c (expand_call): Reorganize somewhat in order
        to avoid unnecesary recalculation inside loop and make
        tail call failure code cleaner.

This broke sparc sibcalls.  Note that initialize_argument_information
is dependant on FUNCTION_INCOMING_ARG, which is of course pass-dependant.

I'm going to revert the patch for now.
