commit 4f14910fa1331398cc695011a6af43a89252b4b1
Author: Andrew Burgess <aburgess@broadcom.com>
Date:   Tue Nov 26 16:21:53 2013 +0000

    Mark entirely optimized out value as non-lazy.
    
    If a value is entirely optimized out, then there's nothing for
    value_fetch_lazy to fetch.  Sequences like:
    
     if (value_lazy (retval))
       value_fetch_lazy (retval);
    
    End up allocating the value contents buffer, wasting memory, for no
    use.
