sparc.md (adddi3): If operands[2] is 4096 and operands[1] is constant...
* config/sparc/sparc.md (adddi3): If operands[2] is 4096 and
operands[1] is constant, calculate the sum and generate movdi.
(addsi3): Similarly. Use SImode in call to arith_4096_operand.
(subsi3): Use SImode in call to arith_4096_operand.
* gcc.c-torture/execute/20001031-1.c: New test.
