Change of strategy in the garbage collector.
...
Previously: when a generation (say 2) is collected,
everything in gen 0 moves to gen 1
everything in gen 1 moves to gen 2
everything in gen 2 moves to gen 3
Now: when a generation (say 2 again) is collected
everything in gen 0 moves to gen 3
everything in gen 1 moves to gen 3
everything in gen 2 moves to gen 3
So, some objects get a leap from young to old if they're lucky to be
in the right time.
Consequences: when an object is moved by the collector, we don't
need to track old->new pointers and masks because all moved objects
are clean now. This both simplifies the collector and makes it more
efficient and might open the door for further optimization
opportunities. For bootstrap time, we get about 5% overall
saving and about 20% GC-time saving. Not bad.

Missing initialization of code_ap and code_ep in ikarus-fasl.c

objects from 5242 pages (almost one page per code object) down

his help, I wouldn't have optimized it in about 10 minutes of
coding time.
