  I missed this testsuite fix in the libstdc++ commit.

Tested x86_64-linux, pushed to trunk.

std::string now has [[nodiscard]] attributes on most members, causing
-Wunused-result warnings for this test.

gcc/testsuite/ChangeLog:

	PR testsuite/106795
	* g++.dg/tree-ssa/empty-loop.C: Use -Wno-unused-result.
