89acdbe044 The ams pool no longer requires a chain argument, but defaults to the arena default chain. 
Chains passed to the AMS pool are no longer required to contain a single generation, though the AMS will only use the first generation by default.

e0c8a8f1c0 The chain parameter to amc is now optional, defaulting to the arena’s default chain. 
AWL and LO accept a chain parameter, and also default to the arena’s default chain, rather than creating their own dummy chains.

4a4ba7d343 The awl and lo pools were allocating their segments along with other pool’s generation 1, while accounting sizes into generation 0. in fact, this “generation 1” was really a kind of placement “clump” and the segments really lived in generation 0. however, this confused the new chainalloc because there are no longer any “clumps” maintained by the arena, causing awlut to fail. fixed awl and lo to be truthful about the generation they’re allocating in. placement concerns have been removed.

6b4100e1b1 Since the dynamic generation is shared between chains (for some reason) using its unified zone set, rather than keeping a special zone set per chain, which would’ve used up more zones. 
Using arena->topGen->mortality for the dynamic generation’s mortality, rather than a global variable.

d8e81ae3c3 Abolishing the redundant generation to zone map in the vm arena, and replacing it with chainalloc, which allocates segments within a generation. 
Generations from different chains will no longer share the same zone sets, and will not be collected together.  To get this behaviour, use the same chain, as documented.
