add compile-toplevel and evaluate conditions to eval-case

* ice-9/boot-9.scm (eval-case): Define two more conditions:
  compile-toplevel and evaluate, as common lisp and chez scheme do.
  (defmacro, define-option-interface, define-macro, define-syntax-macro)
  (define-module, use-modules, use-syntax, define-public)
  (defmacro-public, export, re-export): Add `compile-toplevel' to all
  uses of eval-case.
