middle-end: Add target independent tests for Arm complex numbers vectorization.

middle-end: Add target independent tests for Arm complex numbers vectorization.

This beefs up the complex numbers vectorization testsuite
and adds target independent checks next to the target
dependent ones.

This allows regressions to the detection code to be found
when running on any target, not just aarch64.
