testsuite: enable use of cxa_atexit on tree-ssa cxa_atexit tests

The expected cxa_atexit calls and optimizations won't take place on
targets that don't have -fuse-cxa-atexit enabled by default.  Enabling
it explicitly is enough to meet the expectations of the cxa_atexit
tests.

for  gcc/testsuite/ChangeLog

	* g++.dg/tree-ssa/cxa_atexit-1.C: Enable -fuse-cxa-atexit.
	* g++.dg/tree-ssa/cxa_atexit-2.C: Likewise.
	* g++.dg/tree-ssa/cxa_atexit-3.C: Likewise.
	* g++.dg/tree-ssa/cxa_atexit-4.C: Likewise.
	* g++.dg/tree-ssa/cxa_atexit-5.C: Likewise.
	* g++.dg/tree-ssa/cxa_atexit-6.C: Likewise.
