TestScript is very slow on Plan 9 because this test
is particularly i/o intensive.
This is leading the plan9/386 and plan9/amd64 builders
to time out. This test was already skipped on plan9/arm
because arm is part of the "slow architectures" list.
This change skips TestScript on Plan 9 on short mode.

With b.Loop() in place, the time measurement of loop scaling could be improved to be tighter. By identifying the first call to b.Loop(), we can avoid measuring the expensive ramp-up time by reset the timer tightly before the loop starts. The remaining loop scaling logic of b.N style loop is largely reused.

MapIterNext-8 61.95n ± 0% 54.95n ± 0% -11.28% (p=0.000 n=10)
for the change of `test/escape_reflect.go`:
removing mapiterkey, mapiterelem would cause leaking MapIter content
when calling SetIterKey and SetIterValue,
and this may cause map bucket to be allocated on heap instead of stack.
Reproduce:
```
{
m := map[int]int{1: 2} // escapes to heap after this change
it := reflect.ValueOf(m).MapRange()
it.Next()
var k, v int
reflect.ValueOf(&k).Elem().SetIterKey(it)
reflect.ValueOf(&v).Elem().SetIterValue(it)
println(k, v)
}
```
This CL would not introduce abi.NoEscape to fix this. It may need futher
optimization and tests on hiter field usage and its escape analysis.
