[PATCH] libstdc++: testsuite: Add climits missing test case

[Xavier Bonaventura]

"long long" and "unsinged long long" min and max macros were added in
C++11, but they were not present in the climits test.

libstdc++-v3/testsuite/ChangeLog:

    * 18_support/headers/climits/values_c++11.cc: New test.
