Function CheckMakePairUsesDeduction

tools/cpplint.py:7184–7206

Check that make_pair's template arguments are deduced. G++ 4.6 in C++11 mode fails badly if make_pair's template arguments are specified explicitly, and such use isn't intended in any case. Args: filename: The name of the current file. clean_lines: A CleansedLines instance
