[PATCH 03/13] arm: Add test for PR target/101325

[Christophe Lyon <christophe.lyon@foss.st.com>]

This test is derived from the one provided in the PR: it is a
compile-only test because I do not have access to anything that could
execute it.  We can switch it do 'dg-do run' later, however it would
be better to write a new executable test to ensure coverage in case
the tester cannot execute such code (and it will need a new
arm_v8_1m_mve_hw or similar effective-target).
