cmd/compile: remove pointer temporaries in walkcompare
When comparing two T-typed values t1 and t2 using the T_eq function,
we used to generate:
pl := &t1
pr := &t2
return T_eq(pl, pr, unsafe.Sizeof(T{}))
This CL changes it to simply generate:
return T_eq(&t1, &t2, unsafe.Sizeof(T{}))
Surprisingly, this does not pass toolstash. For some reason, it seems
like SSA wasn't able to SSA-ify the pl and pr variables in all cases.
