[v3,03/15] arm: Add tests for PR target/101325
Commit Message
These tests are derived from the one provided in the PR: there is a
compile-only test because I did not have access to anything that could
execute MVE code until recently.
I have been able to add an executable test since QEMU supports MVE.
Instead of adding arm_v8_1m_mve_hw, I update arm_mve_hw so that it
uses add_options_for_arm_v8_1m_mve_fp, like arm_neon_hw does. This
ensures arm_mve_hw passes even if the toolchain does not generate MVE
code by default.
