* module/language/tree-il.scm (tree-il-fold): Implement using
make-tree-il-folder. This is an incompatible change: there is no more
"leaf" procedure, and tree-il-fold only works on tree-il and not
lists.
* module/language/tree-il/analyze.scm (<tree-analysis>, analyze-tree):
Adapt to tree-il-fold change, losing the "leaf" handler.
(unused-variable-analysis, unused-toplevel-analysis)
(unbound-variable-analysis, arity-analysis): Adapt to tree-analysis
change.
* module/language/tree-il/canonicalize.scm (tree-il-any)
* module/language/tree-il/cse.scm (build-assigned-var-table)
* module/language/tree-il/peval.scm (tree-il-any, build-var-table)
(peval): Adapt to tree-il-fold change.
* test-suite/tests/tree-il.test ("tree-il-fold"): Adapt tests for new
interface and expectations.
* module/language/tree-il.scm (pre-post-order): New helper, like
pre-order! and post-order! but not destructive.
(post-order): Implement in terms of pre-post-order, and rename from
post-order!.
* module/ice-9/compile-psyntax.scm (squeeze-tree-il):
* module/language/tree-il/canonicalize.scm (canonicalize):
* module/language/tree-il/fix-letrec.scm (fix-letrec):
* module/language/tree-il/primitives.scm (resolve-primitives): Use
post-order, and rename from the destructive
variants (squeeze-tree-il!, canonicalize!, etc). Adapt callers.
* test-suite/tests/tree-il.test (strip-source): Adapt to post-order.
* test-suite/tests/cse.test:
* test-suite/tests/peval.test:
* module/language/tree-il/optimize.scm: Adapt callers.

* module/language/tree-il/canonicalize.scm (canonicalize!): Fix a bug in
which the sense of `escape-only?' was reversed. We never saw this
though, because for other reasons, no prompts were being identified as
escape-only.
This was a pretty big merge involving a fair amount of porting,
especially to peval and its tests. I did not update psyntax-pp.scm,
that comes in the next commit.

* module/language/tree-il/peval.scm: Move to its own file. Remove the
bits about <prompt> thunk-application bodies, as they are not
optimizations, simply expectations of the compiler. `canonicalize'
handles that now.
* module/language/tree-il/optimize.scm: Use peval from its module.
Don't call `inline!', as that's useless now.
* module/language/tree-il/canonicalize.scm: New file, implementing a
pass that `compile-tree-il' runs on the result from the optimizer.
The compiler currently expects a <let> form to have bindings, for
example, and this pass turns a <let> without bindings into its body.
* module/language/tree-il/inline.scm: Deprecate, as `peval' does
everything this function ever did.
* module/language/tree-il/compile-glil.scm: Canonicalize after
optimizing. This should allow us to skip the optimizer entirely, if
we want.
* module/Makefile.am: Update and reorder a little bit.
