    Allow arithmetic operators inside C++ template constructs.
    
    Fixes debbugs #22486.
    
    * lisp/progmodes/cc-langs.el (c-multichar->-op-not->>-regexp): New language
    variable.
    (c-<>-notable-chars-re): New language variable.
    
    * lisp/progmodes/cc-engine.el (c-forward-<>-arglist-recur): User
    c-<>-notable-chars-re in place of the former fixed string in searching for
    places to stop and examine.
    Use c-multichar->-op-not->>-regexp to check that a found ">" is not part of 
a
    multichar operator in place of the former c->-op-without->-cont-regexp.
    Add code to skip forwards over a balanced parenthesized expression.
