<p>Instruction aliases can also have a Requires clause to make them
subtarget specific.</p>
+<p>If the back-end supports it, the instruction printer can automatically emit
+ the alias rather than what's being aliased. It typically leads to better,
+ more readable code. If it's better to print out what's being aliased, then
+ pass a '0' as the third parameter to the InstAlias definition.</p>
