178a40928a <prompt> body and handler are lambdas; add escape-only? field
* module/language/tree-il.scm (<prompt>): Change to have the body and
  handler be lambdas, and add an "escape-only?" field.  This will make
  generic prompts work better in CPS or ANF with the RTL VM, as it
  doesn't make sense in that context to capture only part of a frame.
  Escape-only prompts can still be fully inlined.
  (parse-tree-il, unparse-tree-il): Add escape-only? to the
  serialization.
  (make-tree-il-folder, pre-post-order): Deal with escape-only?.

* module/language/tree-il/analyze.scm (analyze-lexicals): Handle
  escape-only?, and the new expectations for the body and handler.

* module/language/tree-il/canonicalize.scm (canonicalize): Ensure that
  the body of an escape-only continuation is a thunk, and that the
  handler is always a lambda.
* module/language/tree-il/debug.scm (verify-tree-il): Assert that
  escape-only? is a boolean.

* libguile/vm-i-system.c (push-fluid, pop-fluid):

  primcalls to push-fluid and pop-fluid.
  (custom-throw-handler, catch, with-throw-handler): Use with-fluid*

  with-fluids.

* libguile/memoize.h (SCM_M_WITH_FLUIDS): Remove definition.

* module/ice-9/psyntax.scm (build-dynlet): Remove; this just supported
  with-fluids, which is now defined in boot-9.

* module/language/tree-il/peval.scm (peval): Factor out
  with-temporaries; probably a bad idea, but works for now.  Factor out
  make-begin0 (a better idea).  Inline primcalls to with-fluid*, and
  remove dynlet cases.

* libguile/eval.c (eval): Remove SCM_M_DYNWIND case.
* libguile/expand.c: Remove scm_sym_at_dynamic_wind.
* libguile/memoize.c (do_wind, do_unwind): A couple of hacky subrs.  If
  we see a wind or unwind primcall, we expand to a call of a quoted subr
  value.  It works and removes a kind of memoized value from the
  interpreter.  For the compiler,primcalls to wind and unwind are
  handled specially.
  (MAKMEMO_DYNWIND): Remove.
  (scm_tc16_memoizer): Remove.  Yay!
  (memoize): Remove speculative lookup for toplevels to see if they are
  memoizers: there are no more memoizers.  Memoize calls to the wind and

  (scm_init_memoize): Add wind and unwind local definitions.

* module/ice-9/boot-9.scm (dynamic-wind): Reimplement in terms of "wind"
  and "unwind" primitives.  These primitives are not exposed to other
  modules.

* module/ice-9/eval.scm (primitive-eval): Remove dynwind case.
* module/language/scheme/decompile-tree-il.scm (do-decompile):
  (choose-output-names): Remove dynwind cases.

* module/language/tree-il/analyze.scm (analyze-lexicals): Remove dynwind
  cases.
