middle-end: Update the Arm complex numbers auto-vec detection to the new format of the SLP tree.
The layout of the SLP tree has changed in GCC 12 which
broke the detection of complex FMA and FMS.
This patch updates the detection to the new tree shape
and by necessity merges the complex MUL and FMA detection
into one.
This does not yet address the wrong code-gen PR which I
will fix in a different patch as that needs backporting.
