MFC r279663,r279666 (pfg):
r279663:
qsort(3): enhance to handle 32-bit aligned data on 64-bit systems
Implement a small enhancement to the original qsort implementation:
If the data is 32 bit aligned we can side-step the long type
version and use int instead.
The change brings a modest but significant improvement in
32 bit workloads.
r279666:
qsort(3): small style(9) cleanups.
Basically spaces vs. tabs.
No functional change.
