Reasons for using the LOC_ARG:

(2) Because registers are often re-used and stack

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 both values.
