cb28c08537 add primitive expander for tree-il
* module/Makefile.am: Add inline.scm.

* module/language/tree-il.scm (pre-order!, post-order!): pre-order! is
  new. post-order! existed but was not public. They do destructive tree
  traversals of tree-il, and need more documentation. Also, add
  predicates to tree-il's export list.

* module/language/tree-il/inline.scm: New file, which expands primitives
  into more primitive primitives. In the future perhaps it will not be
  necessary, as the general inlining infrastructure will handle these
  cases, but for now it's useful.

* module/language/tree-il/optimize.scm: Move post-order! out to better
  pastures.

9efc833d65 add tree-il optimizer
* module/language/tree-il/optimize.scm: New module, for optimizations.
  Currently all we have is resolving some toplevel refs to primitive
  refs.

* module/Makefile.am: Add new module.

* module/language/tree-il.scm: Fix exports for accessors for `src'.

* module/language/tree-il/compile-glil.scm: Tweaks, things still aren't
  working yet.

811d10f5a2 new language: tree-il. psyntax generates it when run in compile mode.
* module/Makefile.am: Add tree-il sources.

* module/ice-9/compile-psyntax.scm: Adjust for sc-expand producing
  tree-il in compile mode.

* module/ice-9/psyntax.scm: Switch from expand-support to tree-il for
  generating output in compile mode. Completely generate tree-il -- the
  output wasn't Scheme before, but now it's completely not Scheme.

* module/ice-9/psyntax-pp.scm: Regenerated.

* module/language/scheme/compile-ghil.scm: Strip structures using
  tree-il, not expand-support.

* module/language/tree-il.scm:
* module/language/tree-il/spec.scm
* module/language/tree-il/compile-glil.scm: New language. It will compile
  to GLIL, though it doesn't yet.
