CC Mode: Fix bug #40052, where a very large macro was too slow in scrolling
* lisp/progmodes/cc-engine.el (c-end-of-macro): Fix faulty cache handling,
where the upper bound of c-macro-cache was never being set.
(c-forward-comment-minus-1): New macro which terminates unwanted indefinite
backward searching with lots of escaped newlines in c-backward-single-comment.
(c-backward-single-comment, c-backward-comments): Use the new macro above.
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings)
(c-after-change-mark-abnormal-strings, c-after-change-escape-NL-in-string):
Optimize three regexps by using shy groups, thus preventing regexp stack
overflow while handling the large C Macro.
