Ben Shi 20046020c4 cmd/compile: fix an issue in MNEG of ARM64
There are two less optimized SSA rules in my previous CL
https://go-review.googlesource.com/c/go/+/95075 .

This CL fixes that issue and a test case gets about 10%
performance improvement.
name    old time/op  new time/op  delta
MNEG-4   263µs ± 3%   235µs ± 3%  -10.53%  (p=0.000 n=20+20)
