5644b901d0 Avoid unnecessary closures in arrow-val-first 
This code uses call-with-values and case-lambda to check the number of
values that returns the original function inside the contract.
The case-lambda create new closures because they have references
to local variables.

In these case, it's possible to avoid the creation of closure saving the
results in temporal variables, that are used later outside the case-lambda.

9e69f341b3 fix unsafe-chaperone-procedure and ...-procedure* side channel 
Also, clarify in docs that `unsafe-chaperone-procedure` cannot
really work with an argument created via `chaperone-procedure*`.

767fd3fa3a Tests for object/c and dynamic-object/c instrumentation. 
Instrumentation which was already there from object-contract.

9d990b65dc Add instrumentation to class/c. 
Method contracts are taken care of by the function combinators.

So only field contract instrumentation is necessary.

bea67c0a39 When we know that the procedure getting a contract is "simple enough", 
drop the tail call fanciness

"simple enough", for now, means that it is a struct selector, predicate,
constructor, or mutator. Perhaps we will learn more about such simple
procedures where this is safe some other way.

This commit speeds up this program:

  #lang racket/base
  (require racket/contract/base)
  (struct s (x))
  (define f (contract (-> any/c integer?) s-x 'pos 'neg))
  (define an-s (s 1))
  (time
   (for ([x (in-range 10000000)])
     (f an-s)))

126c090579 special case any/c when it appears syntactically in the argument to -> 
Skip calling the domain projection in that case and, if all of the
arguments are any/c then also skip putting the contract continuation mark

This appears to give about a 20% speed up on this program:

  #lang racket/base
  (require racket/contract/base)
  (define f
    (contract
     (-> any/c integer?)
     (λ (x) 1)
     'pos 'neg))
  (time
   (for ([x (in-range 4000000)])
     (f 1)))

86f0d75a96 JIT: fix fast path for property-only chaperones 
The recently added fast path for property-only chaperones did not
propagate the original object in the case that the property-only
chaperone wraps a `chaperone-procedure*` chaprerone.
