    go: Replace uses of {FLOAT,{,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 {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE
    in go with TYPE_PRECISION of {float,{,long_}double}_type_node.

    gcc/go/ChangeLog:
    
            * go-gcc.cc (Gcc_backend::float_type): Use TYPE_PRECISION of
            {float,double,long_double}_type_node to replace
            {FLOAT,DOUBLE,LONG_DOUBLE}_TYPE_SIZE.
            (Gcc_backend::complex_type): Likewise.
