[AArch64 Testsuite obvious] Reinstate torture-init and torture-finalize in advsimd-intrinsics.exp

[James Greenhalgh <james dot greenhalgh at arm dot com>]

Hi,

advsimd-intrinsics.exp is polluting set-torture-options without
cleaning up after itself. This manifests as a failure in
aarch64-none-linux-gnu testing:

  FAIL: gcc.dg/torture/builtin-cproj-1.c   -Og -g  (test for excess errors)

This test does not expect to be called with -Og and will fail if you
do so.

There is a different question about whether we want to enable -Og
testing in dg-torture.exp , in which case this test will need patched
up. But regardless of that decision, advsimd-intrinsics.exp should
not clobber the set-torture-options without good reason.

Fixed by wrapping the main loop of advsimd-intrinsics.exp in torture-init
and torture-finish.

Tested with an aarch64-none-linux-gnu cross build to ensure it
clears the issue I was seeing.

Applied as revision 224507.

Thanks,
James
