583ca906b3 Significantly reduce dependencies. 
In conjunction with a small change to syntax/parse, this means
that `typed/racket/base` no longer depends on `racket/set`,
`racket/contract/base`, or `racket/generic`.

Timings on my machine go from ~200ms for `#lang typed/racket/base`
as the whole file, to ~100ms. For comparison, `racket/base` is 30ms
and `#lang racket` is 150ms. `#lang typed/racket` is ~200ms with
this change.

Changes include:
 - not using `in-syntax`
 - switching to `syntax/parse/pre`
 - avoiding `template` from `syntax/parse`

c70910aaa0 Fix type restriction in values->tc-results 
Previously the restriction didn't account for traversing
the object type with the given path. This also relies on
the previous commit that adds subtyping on filters.

(because this change seems to introduce filters which
 only differ by an unrolling of a recursive type, but
 the old subtyping only worked for identical types)

8acc86bb9b Add subtyping for types inside filters 
This makes a type like

  (-> Any Boolean : #:+ Integer)

a subtype of a type like

  (-> Any Boolean : #:+ Number)

For not filters, the direction is reversed.

ee7bed777b Add dependency on 6.2.0.2. 
This is definitely needed for the new `begin-encourage-inline`
submodule, but also needed for various other changes (such as
`dynamic-object/c`).

0dce19e4bf Reduce more dependencies. 
Use `syntax/parse/pre` (checked with @rmculpepper).
Use new `begin-encourage-inline` submodule.
Remove use of `match` in TR runtime-loaded code.

4709536653 Split prims.rkt to reduce dependencies. 
There are several new files: one for structure prims, one for
annotation-related prims, one for contract related ones. The prims-contract
file uses trickery with submodules to avoid a direct dependency
on `racket/contract`.

Additionally, the rewritten versions of `for/set` et al now use
a submodule to avoid a direct dependency on `racket/set`.

Allow more cases that are allowed for ordinary function
contracts and explicitly error instead of internal errors
for other cases.

(order-of-magnitude n) is only negative if n < 1. Hence it is non-negative for all positive integers.

011649a654 move contract submodules to start of enclosing module 
Putting the contract submodules early enough allows them to be used
for `module*` submodules.
