Cuong Manh Le 0a02371b05 cmd/compile: set correct type for OpIData 
Since CL 270057, there're many attempts to fix the expand_calls pass
with interface{}-typed. But all of them did not fix the root cause. The
main issue is during SSA conversion in gc/ssa.go, for empty interface
case, we make its type as n.Type, instead of BytePtr.

To fix these, we can just use BytePtr for now, since when itab fields
are treated as scalar.

No significal changes on compiler speed, size.
