[dev.ssa] cmd/compile: fix build for old backend on ARM64
Apparently the old backend needs NEG instruction having RegRead set,
even this instruction does not take a Reg field... I don't think SSA
uses this flag, so just leave it as it was. SSA is still happy.
Fix ARM64 build on https://build.golang.org/?branch=dev.ssa
