[Dwarf-Discuss] variable locations - safe use as lvalues

With split lifetimes, the debugger can ask the user which of the lifetimes the user wants to set. 

    debugger-prompt> set A = 3
    Variable 'A' has more than one location.  Choose which to set:
    1.	The location used in lines 112 and 120
    2.	The location used in line 111
    3.	All locations
    4.	None (no change)

A less sophisticated debugger might just do this:

   debugger-prompt> set A = 3
    Variable 'A' has no unique location to set.

...based on looking at the 'assign' location list.
