6603fe3ad4 cs: improve single-value and no-return tracking
New `#%app/no-return` and `#%app/value` functions at the Chez Scheme
level allow schemify to communicate that function calls will not
return or will return a single value. The schmeify pass may have this
information because a Racket-level primitive is declared that way
(such as `error` or `raise-argument-error` for no-return, or most
functions for single-valued) or because single-valuedness is inferred.

There's currently no inference for no-return functions, because those
are relatively rare. An `#%app/value` is used by schemify only for
imported, non-inlined functions, since cp0 can already deal with local
functions and primitives.

There's a start here at adapting the "optimize.rktl" test suite for CS
--- and that effort triggered these improvements plus some other
low-hanging fruit. But a lot more is needed to adapt "optimize.rktl"
and to make some additional optimizations happen.

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.

b2a27ef05c cs & raco decompile: expose more fasl content
Show the machine code that constructs lifted constants for a linket.

Also, add a `--partial-fasl` option that shows fasl content in a rawer
form, which is useful for checking how content is presented and that
nothing is getting lost in other reconstructed views.

66547f3aaf Change else in match to _
This fixes at least one "potential" bug in the file
`collects/pkg/private/create.rkt`, where `else` in the
`cond` is bound to `else` from `match` instead of `racket/base`.
(though it turns out that the format will always be
truthy, making the program happen to be correct.)

linklet functions.

2a7d94d89c update compilation info, especially for CS
Update the Guide's performance section with current information for
Racket CS, and also document the Racket CS compilation mode and
inspection environment variables. Make a couple of environment
variables work more consistently: PLTDISABLEGC for CS and PLT_ZO_PATH
for BC.

machine code in a Racket CS linklet.

6e958b627f expander: avoid VM-specific expansion
Move different handling of serialized syntax data to the schemify
layer instead of te expander, so that the result of compiling in
machine-independent form is the same for traditional Racket and Racket
CS.

8b917039a2 zo-{parse,marshal}: round-trip all ".zo" formats
Although `raco dec` cannot yet usefully decompile Racket CS compiled
code, the underlying `zo-parse` and `zo-marshal` functions can now at
least read and re-write that format by just keeping the bytes for the
CS-specific part, and it can also now rouind-trip the machine- and
VM-independent format.

4396b841c0 fix expander+compiler to report source name for use-before-init
Lots of plumbling was in place to preserve the source name (instead of
the symbol generated to avoid collisions for macro-introduced
definitions), but some small pieces were missing.

Closes #2288

59ef254318 switch to a new, Racket-implemented expander & module system
This commit merges changes that were developed in the "racket7" repo.
See that repo (which is no longer modified) for a more fine-grained
change history.

The commit includes experimental support for running Racket on Chez
Scheme, but that "CS" variant is not built by default.
