* module/system/il/ghil.scm (<ghil-env>, <ghil-toplevel-env>): Refactor so that all environments point (eventually) at one toplevel environment. Instead of having potentially multiple toplevel environments, each noting the module against which its bindings are resolved, have each binding in the toplevel record what module it should be resolved in. Should fix compilation units that define multiple modules. (ghil-lookup, ghil-define): Reworked to not be destructive. Module variables now have the module name as their "env", and are keyed as `(MODNAME . SYM)' in the var table. (call-with-ghil-environment): Reindented. * module/system/il/inline.scm (try-inline-with-env): Adapt to env/toplevel changes. * module/system/vm/assemble.scm (dump-object!): A vlink-later now holds the module name, not the module itself. * module/system/il/compile.scm (make-glil-var): The "env" of a "module" var is now the module name, not the module. * module/language/scheme/translate.scm (primitive-syntax-table): Update the way we test for toplevel environments. Reindent the lambda translator. (lookup-transformer, trans): lookup-transformer now has 2 args, not 3. (translate): Update the way we make toplevel environments.
