d3d2795fce Improve control over checking: 
1. Where Type is a pointer type with a signature, replace CHECKL(TypeCheck(val)) with CHECKD(Type, val).
2. Where Type is a pointer type with no signature, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val).
3. Where Type is a pointer type with a signature, but the structure is not visible at point of checking, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val). Reference <design/check/#.hidden-type>
4. Make BTCheck extern and use it where possible.
5. Replace AVER(TypeCheck(val)) with AVERT(Type, val).

4b50f3688b Adding mps_key_gen generation keyword to pools that take a chain (except amc), so that you can specify which generation to allocate in by default. this allows some flexibility when the client can predict the lifetimes of objects. 
The AWL and LO pools allocate into generation 1 of the arena default chain if neither MPS_KEY_CHAIN or MPS_KEY_GEN is specified, simulating the default setup before the chain-zones branch.

e02a69f88b 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.

f1abe0e30f 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.
