3a99a19c56 reduce double major GCs 
When a major GC triggers finalization, another major
GC is scheduled immediately on the grounds that the
finalizer may release other values. That was important
at once time, but the finalization and weak-reference
implementation has improved to the point where the
extra ful GC no longer seems necessary or useful.

9711000b70 drop generation 1/2 except in incremental mode 
Originally, generation 1/2 was intended to delay major
collections when the heap is especially large. It doesn't
seem to be effective in that case, and it can slow down
minor GCs, so continue to use it only in incremental
mode (where it helps significantly with fragmentation).

6957780cd5 incremental GC: tune departure from incremental mode 
At the completion of an incremental major GC, if incremental
mode wasn't requested recently, schedule an immediate major
GC to reduce the heap back to its normal footprint.

074202bdd2 raco setup: don't completely ignore a collection without compilation 
A collection's "info.rkt" might have `(define compile-omit-paths
'all)` but also other setup actions, so don't completely ignore
a collection directory just because there's nothing to compile.

f7c67f5c45 incremental GC: always use generation 1/2 in incremental mode 
Also, make nursery 1/4 as big in incremental mode, and
correspondingly tune the amount of work to perform per
collection by 1/4 its old value. Using generation 1/2
reduces fragmentation that would otherwise be increase
by a smaller nursery.

d01aec1b32 JIT: always use buffer padding of 200 
The main intent of this change is to raise the buffer size
for ARM, but that would leave only 32-bit x86 at size 100, so
just make it size large for all machines.

3d7d906cc1 tweak and clean up the contract combinators api 
- uniformly remove the extra layers of calls to unknown functions for
  chapereone-of?  checks that make sure that chaperone contracts are
  well-behaved (put those checks only in contracts that are created
  outside racket/contract)

- clean up and simplify how missing projection functions are created
  (val-first vs late-neg vs the regular ones)

- add some logging to more accurately tell when late-neg projections
  aren't being used

- port the contract combinator that ->m uses to use late-neg

- port the </c combinator to use late-neg
