* slime-tests.el (compile-defun): Test split into two parts.
(compile-defun-with-reader-characters): Split from `compile-defun'
as CCL does not pass this part.
* .travis.yml: added targets to include CCL 1.9 for Travis builds
* contrib/test/slime-autodoc-tests.el: Mark several tests as failing for
CCL 1.9
