toplev.c (rest_of_compilation): Set bct_p on second call to loop_optimize.

        * toplev.c (rest_of_compilation): Set bct_p on second call to
        loop_optimize.
        * loop.c (loop_optimize, scan_loop, strength_reduce): New argument
        bct_p.
        (strength_reduce): Only call analyze_loop_iterations and
        insert_bct if bct_p set.
        (check_dbra_loop): Fix typo.
        (insert_bct): Use word_mode instead of SImode.
        (instrument_loop_bct): Likewise.  Do not delete iteration count
        condition code generation insn.  Initialize iteration count before
        loop start.
        * rtl.h (loop_optimize): Update prototype.
        * ginclude/va-ppc.h (va_arg): longlong types in overflow area are
        not doubleword aligned.
        * rs6000.c (optimization_options): New function.
        (secondary_reload_class): Only call true_regnum for PSEUDO_REGs.
        * rs6000.h (OPTIMIZATION_OPTIONS): Define.
        (REG_ALLOC_ORDER): Allocate highest numbered condition regsiters
        first; cr1 can be used for FP record condition insns.
