aarch64: Add testcase for PR97405

This aarch64 sve specific code was fixed by r15-917-gc9842f99042454
which added a riscv specific testcase so adding an aarch64 one to test
the fix does not regress is a good idea.

Committed as obvious after testing the testcase for aarch64-linux-gnu.

	PR tree-optimization/97405

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/sve/pr97405-1.c: New test.
