Allow re-assigning to convenience variables
A customer reported somewhat odd gdb behavior, where re-assigning an
array or string to a convenience variable would yield "Too many array
elements". A test case is:
(gdb) p $x = "x"
(gdb) p $x = "xyz"
This patch fixes the problem by making a special case in the evaluator
for assignment to convenience variables, which seems like the correct
behavior.
Note that a previous patch implemented this for Ada, see commit
f411722cb ("Allow re-assigning to convenience variables").
