fixed_point: Make to_uint() non-const

This calls round_up(), which is a non-const member function, so if a
fixed-point instantiation ever calls to_uint(), it'll result in a
compiler error.

This allows the member function to work.

While we're at it, we can actually mark to_long_floor() as const, since
it's not modifying any member state.
