+ (2) because registers are often re-used and stack slots

+
+ Reasons why we might want to use the LOC_REGISTER:
+ (1) So that the backtrace prints the same value as
+ "print foo". I see no compelling reason why this needs
+ to be the case; having the backtrace print the value which
+ was passed in, and "print foo" print the value as modified
+ within the called function, makes perfect sense to me.
+
+ Additional note: It might be nice if "info args" displayed
