libstdc++: Replace uses of _GLIBCXX_USE_INT128 in testsuite

Since r12-435 the _GLIBCXX_USE_INT128 macro is never defined, so all
uses of it in the testsuite are wrong. The tests should be checking
__SIZEOF_INT128__ instead.

Also add some tests for an INT_3 type, which were missing.

libstdc++-v3/ChangeLog:

	* testsuite/18_support/numeric_limits/40856.cc: Replace use of
	_GLIBCXX_USE_INT128.
