Emulate 8-bit CAS using 32-bit CAS. Cannot be used if the buffer length is not a multiple of 4 and too short for the 32-bit access to be fully in bounds.

compareExchangeInt16

public int compareExchangeInt16(ByteBuffer buffer,
                                int index,
                                int expectedValue,
                                int newValue)

Emulate 16-bit CAS using 32-bit CAS. Cannot be used if the buffer length is not a multiple of 4 and too short for the 32-bit access to be fully in bounds, or if the index is odd.
