Hi All,
The sharing of the COMPLEX_MUL node makes it so it's
more efficient to not generate both a MUL and FMA
in this node.
Because the shape for a normal FMA is not different
the FMA is no longer detected here which results in
better codegen so update the testcase.

When range-of_stmt is invoked on a statement, out-of-date updating is
keyed off the timestamp on the definition.
When the def is calculated, and its global value stored, a timestamp is

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

Since retslot it essentially a hidden argument that is known to be write-only
we can do pretty much the same stuff as we do for regular parameters.
