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.

Regtested on aarch64-none-linux-gnu and no issues.

Committed under the GCC obvious rule.

Thanks,
Tamar
