1687         * simplify-rtx.c (simplify_const_unary_operation): Use
1688         is_a <scalar_int_mode> instead of checking for a nonzero
1689         precision.  Forcibly convert op_mode to a scalar_int_mode
1690         in that case.  More clearly differentiate the operand and
1691         result modes and use the former when deciding what the value
1692         of a count-bits operation should be.  Use is_int_mode instead
1693         of checking for a MODE_INT.  Remove redundant check for whether
1694         this mode has a zero precision.

15165         This is due to the power6 not having a 32-bit integer store
