Remove Multidefs

Multidefs are a bit unwieldy and incomplete.  Remove them in favor of
another mechanism, probably for loops.

-A multidef takes three "arguments" in the &lt;&gt; notation after the multidef 
-name.  The first is a list of items to process.  The second is a declaration.  
-This declaration creates a temporary name used as an iterator.  It picks up the 
-value of each processed list item as TableGen generates defs from the multidef.  
-This temporary may be named and passed into the multidef body as shown in the 
-example above.  This provides a powerful way to generate defs with various 
-values from a single multidef.  The final "argument" is an integer value 
-indicating where in the list to begin processing.  In the above example we 
-chose to begin list processing with the third item (index 2).
