Handle in-vector

...
* Add `normalise-inputs` to special function env.
* Treat eta-expansion specially. Now
`(lambda (x ...) (f x ...))`
will typecheck like `f` but with a type restricted to
the size of `x ...`.
Currently, this special case only works for non-polymorphic
functions.

safe & efficient (-> Any Boolean) contract
...
New strategy for compiling the (-> Any Boolean) type to a contract.
When possible, uses `struct-predicate-procedure?` instead of
wrapping in `(-> any-wrap/c boolean?)`.
Makes exceptions for untyped chaperones/impersonators over struct predicates;
those are always wrapped with `(-> any-wrap/c boolean?)`.
This change also affects (require/typed ... [#:struct ...]), but not #:opaque

As of this moment, the performance win on new-metrics.rkt for
using the unsafe version is about 1% (avg over 10 runs), which
isn't enough to make it worth the segfaults. I believe that
changes to the JIT since 2012 (when the unsafe ops were added)
have sped up struct access.
