Split `org-emph-re' and `org-verbatim-re'
* lisp/org.el (org-set-emph-re): Refactor code. Rip "~" and "=" markers off `org-emph-re'. (org-do-emphasis-faces): (org-sort-remove-invisible): Handle both `org-emph-re' and `org-verbatim-re'. (org-in-verbatim-emphasis): Use `org-verbatim-re' instead of `org-emph-re'. * lisp/org-element.el (org-element-code-parser): (org-element-verbatim-parser): Use `org-verbatim-re' instead of `org-emph-re'. * testing/lisp/test-org-element.el (test-org-element/bold-parser): (test-org-element/code-parser): (test-org-element/italic-parser): (test-org-element/strike-through-parser): (test-org-element/underline-parser): (test-org-element/verbatim-parser): Update tests, which no longer need to bind `org-emph-re'.
