Revert "Cleanup QSemaphore and make it always 64bit large"
This reverts commit ff69227a49119c00f703cf89c9d72db7eeeeaa66.
Reason for revert: 64-bit atomics on 32-bit systems are often
(but not always) worse than the 32-bit semaphore as it was
implemented. Plus the High32 and Low32 functions are returning
the same thing, forgetting the endianness check.
