        * rtl.h (rtl_size): Declare.
        (rtunion): Remove rtwint.
        (rtx_def): Replace 'fld' with a union of an rtunion or a HOST_WIDE_INT.
        (RTX_HDR_SIZE, RTX_SIZE): New macros.
        (RTL_CHECK1): Adjust for new rtx_def layout.
        (RTL_CHECK2, RTL_CHECKC1, RTL_CHECKC2): Likewise.
        (XWINT, XCWINT): Likewise.  Access the rtx structure directly.
        (X0WINT): Remove.
        (X0ANY): New macro.
