implement autocompilation
* am/guilec (.scm.go): Set GUILE_AUTO_COMPILE=0 when compiling individual
files, and remove the mkdir -p as compile-file takes care of that now.
* libguile/load.c (do_try_autocompile, autocompile_catch_handler)
(scm_try_autocompile, scm_init_load): Implement autocompilation.
* libguile/script.c (scm_shell_usage, scm_compile_shell_switches): Add
--autocompile / --no-autocompile command-line options, and support for
the GUILE_AUTO_COMPILE environment variable, defaulting to
autocompilation enabled.
