7904 * simplify-rtx.c (simplify_const_unary_operation): Use
7905 is_a <scalar_int_mode> instead of checking for a nonzero
7906 precision. Forcibly convert op_mode to a scalar_int_mode

7908 result modes and use the former when deciding what the value
7909 of a count-bits operation should be. Use is_int_mode instead
7910 of checking for a MODE_INT. Remove redundant check for whether
7911 this mode has a zero precision.
