    darwin: Replace use of LONG_DOUBLE_TYPE_SIZE
    
    Joseph pointed out "floating types should have their mode,
    not a poorly defined precision value" in the discussion[1],
    as he and Richi suggested, the existing macros
    {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE will be replaced with a
    hook mode_for_floating_type.  To be prepared for that, this
    patch is to replace use of LONG_DOUBLE_TYPE_SIZE in darwin
    with TYPE_PRECISION of long_double_type_node.

    gcc/ChangeLog:
    
            * config/darwin.cc (darwin_patch_builtins): Use TYPE_PRECISION of
            long_double_type_node to replace LONG_DOUBLE_TYPE_SIZE.
