-  Performs an atomic compare exchange operation on a 64-bit unsigned integer.
-
-  Performs an atomic compare exchange operation on the 64-bit unsigned integer specified
-  by Value.  If Value is equal to CompareValue, then Value is set to ExchangeValue and
-  CompareValue is returned.  If Value is not equal to CompareValue, then Value is returned.
-  The compare exchange operation must be performed using MP safe mechanisms.

-  @param  CompareValue  64-bit value used in compare operation.
-  @param  ExchangeValue 64-bit value used in exchange operation.

-  @return The original *Value before exchange.
