refactor(parser): share callee-name parsing and make operator out-param optional

ParseOperatorName() takes an optional int * so callers that ignore the
operator token no longer declare a dummy. The identical identifier-or-
OPERATOR prologues of assignment, identifier-expression and CALL parsing
move into ParseCalleeName().
