CC Mode: in certain font lock loops, check point is not beyond limit.

Browse source 
* /lisp/progmodes/cc-fonts.el (c-font-lock-enum-body)
(autodoc-font-lock-line-markup): As part of the `while' condition, check that
the previous iteration of the loop hasn't moved point past `limit', thus
obviating "wrong side of point" errors in re-search-forward, etc.
