Does the compiler add or omitted unused gates ?

For example, if I had a 74244 buffer, and only used 4 buffers, and I do not connected the other 4 buffers to anything, would the compiler still add those unused gates into the PLD logic blocks ? Or ...

With an FPGA/CPLD, you're not implementing a component, like an old TI part, in the device. You are creating buffers and logic that are implemented using device resources. So if you have 4 buffers in a design, logic resources for 4 buffers will be implemented in the device.
