* 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.
