Subject: stdarg.h: Include va-mn10300.h.

        * ginclude/stdarg.h: Include va-mn10300.h.
        * ginclude/varargs.h: Likewise.
        * ginclude/va-mn10300.h: New file.
        * mn10300/mn10300.c (expand_prologue): If current_function_varargs is
        nonzero, then flush d0/d1 back into the stack.
        (mn10300_builtin_saveregs): New function.
        (function_arg, function_arg_partial_nregs): New functions.
        (initial_offset): Tweak now that the RP save area is allocated
        and deallocated around each call again.
        * mn10300/mn10300.h (FIRST_PARM_OFFSET): Now 4.
        (FRAME_POINTER_REQUIRED): Require a frame pointer for all non-leaf
        functions.
        (REG_PARM_STACK_SPACE): Now 8 bytes.
        (FUNCTION_ARG_REGNO_P): Update for new parameter passing conventions.
        (CUMULATIVE_ARGS, INIT_CUMULATIVE_ARGS): Likewise.
        (FUNCTION_ARG_ADVANCE, FUNCTION_ARG): Likewise.
        (FUNCTION_ARG_PARTIAL_NREGS): Likewise.
        (TRAMPOLINE_TEMPLATE): Don't clobber d0 anymore.
        (TRAMPOLINE_SIZE, INITIALIZE_TRAMPOLINE): Corresponding changes.
        (EXPAND_BUILTIN_SAVEREGS): Define.
        * mn10300/mn10300.md (call, call_value patterns): Allocate and
        deallocate a stack slot for the return pointer around each call.

        * mn10300/mn10300.h (RTX_COSTS): Refine.
        (CASE_VALUES_THRESHHOLD, NO_FUNCTION_CSE): Likewise.
        * mn10300/mn10300.c (output_tst): New function.
        * mn10300/mn10300.md (movdi, movdf): Improve code to load constants
        into registers.
        (tst insns): Use output_tst to optimize some cases.  Add versions to
        encourage more zero extensions instead of sign extensions of HImode
        and QImode values.
        (divsi3, udivsi3): Remove patterns.  Replaced by...
        (divmodsi4, udivmodsi4): New expanders/patterns.
        (andsi3): Optimize "and" operations with certain constants.
