* fold-const.c (fold_convert): For floating point to integer
conversions, return the maximum/minimum representable integer
value if the real constant overflows the destination type.
* tree.c (real_value_from_int_cst): Allow the type to be NULL,
meaning don't truncate the result to a floating point mode.
Simplify the logic by calling real_from_integer directly.
* simplify-rtx.c (simplify_unary_operation): Implement the
same semantics for folding floating point to integer conversions
in RTL.
* gcc.c-torture/execute/20031003-1.c: New test case.
