Motivation: dtrace is extrmely useful when debugging allocation related issues. This adds two scripts that have helped me many times. Modifications: - `dev/malloc-aggregation.d` which prints an aggregation of all stacks that have allocated - `dev/boxed-existentials.d` which live prints all allocations of boxed existentials Result: sharing debugging tools is great
