* fold-const.c (negate_expr_p) <RSHIFT_EXPR>: We can optimize
-((int)X>>C) where C is an integer constant one bit less than the
size of X into (unsigned)X>>C. Similarly for unsigned->signed.
(negate_expr) <RSHIFT_EXPR>: Implement the above transformations.
* simplify-rtx.c (simplify_unary_operation): Also implement the
above transformations at the RTL level.
* gcc.c-torture/execute/20040311-1.c: New test case.
