Nope.  The difference is that the front end has some knowledge of
"this is a new program" versus "this is the same program being
reloaded", because it issued the command in response to some user
stimulus.  GDB has no way to know why the command was issued; in one
case deleting breakpoints is appropriate, in the other it is not.

So if the front end wants breakpoints deleted, I think it's reasonable
for it to do so explicitly.
