rework late binding resolution to be simpler and more efficient
* libguile/programs.h (struct scm_program): * libguile/programs.c (scm_c_make_program): Record the current module when making a program. This replaces the per-late binding recorded module in the generated code, which should be more efficient, both in terms of garbage, and in not calling resolve-module. (program-module): New accessor. * module/system/vm/program.scm: Add program-module to exports. * libguile/vm-i-loader.c (link-later): Remove this instruction, since now the entry in the object table is just a symbol, and can be loaded with load-symbol. * libguile/vm-i-system.c (late-variable-ref, late-variable-set): Rework so as to look up in the module of the current program. The logic could be condensed quite a bit if scm_module_lookup () knew what to do with mod==#f. * module/system/vm/assemble.scm (dump-object!): Dump <vlink-later> just as load-symbol, as mentioned in the note on link-later. * module/system/il/ghil.scm: Update comment to reflect the new reality.
