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.
