Ha, I hesitated earlier to mention that CompareWord and CompareDWord are
~4 times slower than equivalent (on the same number of bytes)
CompareMem/CompareByte calls :) Cool, times with latest FPC (rev 17651):

CompareMem: 1.928s
CompareWord: 1.270s
CompareDWord: 1.108s

These times directly help in my algorithm (I use it to aggressively
search for pairs of matching edges for shadow volumes). Great!
