42847ea523 follow up to William J. Bowman's commit 
- put the tests together with the other define-union-language tests
- fix the docs
- add a release note
- construct the merged language a bit more directly
- properly deal with this kind of thing:
  (define-language L1 (e f ::= 1 2 3))
  (define-language L2 (e g ::= 4 5 6))
  (define-union-language L L1 L2)

b0db8798b6 Changed `define-union-language' to merge nonterminals and their 
right-hand-sides instead of causing an error when more than one language
in the union defines the same nonterminal.

44dd4acb44 Additional random test generation capability for Redex. 
This adds the option to generate random terms that satisfy
judgment-forms and metafunctions.

Currently functionality does not include:
- patterns/terms using: ellipses, in-hole/hole and relatives, side-conditions, unquotes
- define-relation
- redex-check integration

5cbdf4dc76 Provide `main' too, since it's used by redex/tests/run-tests.

4c2940a6d9 Simplify away uses of "-t" in `drdr:command-line'. 
In some cases use `module+' to make the code run nicely without a "-m".

(And some other minor tweaks.)

55b3d99d78 adjust beaucoup places in redex where the source was being 
included in the compiled files. (also, misc minor cleanups
notably a new exercise in tut.scrbl)

closes PR 12547 --- there are still a few uses left, but they do not
seem to be coming from Redex proper:

 - /Users/robby/git/plt/collects/racket/private/map.rkt still appears
   in a bunch of places (there is a separate PR for that I believe),
   and

 - /Users/robby/git/plt/collects/redex/../private/reduction-semantics.rkt
   appears in tl-test.rkt, but I do not see how it
   is coming in via Redex code, so hopefully one of the other
   PRs that Eli submitted is the real cause. If not, I'll revisit later

0c6e0a11cf removed ambiguity from the cont-mark-transform's "a" non-terminal 
Redex no longer has extra checks to eliminate redundant matches
(as those checks are prohibitively expensive for the lambdajs model)
so redundancy in the grammar can, when combined with context
decomposition or named patterns, lead to significant slowdowns

5dcbedc768 redex: adjust the caching strategy 
Instead of using a hash-table, use the equal-hash-code directly;
this lets me evict entries only when they clobber each other,
and generally keep good cache utilization.

Also, cut the cache size by a factor of 5 while still having a
slight performance improvement on the r6rs test suite benchmark.
On that same benchmark, there are 1714812 misses in the cache, but
only 3485 times is an entry in the cache clobbered
