Add %auto-compilation-options', used by compile-file' when auto-compiling.

* module/ice-9/boot-9.scm (%auto-compilation-options): New variable.
  (load-in-vicinity): Honor it.

* libguile/load.c (kw_opts, sym_compile_file,
  sym_auto_compilation_options): New variables.
  (do_try_auto_compile): Honor %AUTO-COMPILATION-OPTIONS.

* module/system/repl/common.scm (repl-default-options): Have
  `compile-options' default to %AUTO-COMPILATION-OPTIONS.
