Subject: [PATCH] c++: Require C++11 for g++.dg/opt/pr110879.C [PR110879]

The _M_realloc_insert member does not have the trivial relocation
optimization for C++98, which seems to be why the _M_end_of_storage
member does not get optimized away. Make this test unsupported for
C++98.

gcc/testsuite/ChangeLog:

	PR libstdc++/110879
	* g++.dg/opt/pr110879.C: Require C++11 or later.
