This patch fixes failures due to the use of 64-bit atomic

Note: this does NOT address the failure on ppc-darwin, which will be addressed
by another patch soon.

* s-atopri.adb (Lock_Free_Try_Write_X): Atomic_Compare_Exchange_X
replaced by Sync_Compare_And_Swap_X.
(Lock_Free_Try_Write_64): Removed.
* s-atopri.ads (Sync_Compare_And_Swap_X): Replaces previous
routine Atomic_Compare_Exchange_X.
(Lock_Free_Read_64): Renaming of Atomic_Load_64.
(Lock_Free_Try_Write_64): Renaming of Sync_Compare_And_Swap_64.
What is the nature of the atomic failures using the
__atomic_compare_exchange built-in? Does it have anything to do with
the expected value being returned by pointer?
