Matthew Flatt f07c2fea71 cs: simplify and improve handling of literals
Use data instead of code to shrink ".zo" sizes by 10-30%.

When Racket code contains a literal that cannot be serialized directly
by Chez Scheme (such as a keyword or an immutable string that should
be datum-interned), the old approach was to generate Scheme code to
construct the literal through a lifted `let` binding. To handle paths
associated with procedures, however, Chez Scheme's `fasl-write` had
been extended to allow arbitrary values to be intercepted during fasl
and passed back in to `fasl-read`. Using that strategy for all Racket
literals simplifies the implementation and reduces compiled code. It
also makes closures smaller, while increases the number of
relocations. DrRacket's foorprint shrinks by about 1%, but the main
affect is on disk space for a Racket installation.

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.

This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.

Quick Start

Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at

https://download.racket-lang.org

Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at

https://docs.racket-lang.org

Building from Source
