Add an accompanying option to the 'frame variable -w' command to, instead of watching the variable,

watch the location pointed to by the variable.  An example,

(lldb) frame variable -w write -x 1 -g g_char_ptr
(char *) g_char_ptr = 0x0000000100100860 ""...
Watchpoint created: WatchpointLocation 1: addr = 0x100100860 size = 1 state = enabled type = w
    declare @ '/Volumes/data/lldb/svn/trunk/test/functionalities/watchpoint/hello_watchlocation/main.cpp:21'

...

(lldb) c

   30  	
(lldb) 

Also add TestWatchLocation.py test to exercise this functionality.
