[Bug 1256283] Re: go tests failing on AArch64

[Michael Hudson-Doyle]

Oh, I misread the cplx2 failure.  Here's a smaller test case:

package main

func main() {
	c5 := 1 + 3i
	cd := c5 / c5
	println(cd)
	if cd != 1+0i {
		println("fail")
	}
}

Cross-compiling and running on the foundation model this gives:

(+1.000000e+000-1.665335e-017i)
fail

so it appears to be some kind of problem with complex division...
