aarch64: fix `mangle_5.C` test

The `volatile` type qualifier is deprecated on function parameters and
return types since C++ 20. This caused extra warning to be emmitted, so
the test failed. Fix it by suppressing the warning.

gcc/testsuite/ChangeLog:

	* g++.target/aarch64/sve/acle/general-c++/mangle_5.C: Fix test.
