0081f17f14 archive/{zip,tar}: fix Writer.AddFS to include empty directories
This change modifies the `(*Writer).AddFS` implementation in both `archive/zip`
and `archive/tar` to always write a directory header. This fixes a bug where
any empty directories in the fs were omitted when a zip or tar archive was
created from `AddFS` method.

Fixes #66831

7c72dc77a9 cmd/go: skip TestScript on Plan 9 in short mode
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.

402dc98759 testing: enable better loop time measurement for benchmarking.
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.

For #61515.

7ba074fe43 reflect: remove calling mapiterkey, mapiterelem
It makes use of the hiter structure which matches runtime.hiter's.

This change mainly improves the performance of Next method of MapIter.

goos: darwin
goarch: arm64
pkg: reflect
cpu: Apple M2
              │  ./old.txt  │              ./new.txt              │
              │   sec/op    │   sec/op     vs base                │
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.

Fixes #69416

5367d696f7 math/big: simplify divBasic ujn assignment
Rather than conditionally assigning ujn, initialise ujn above the
loop to invent the leading 0 for u, then unconditionally load ujn
at the bottom of the loop. This code operates on the basis that
n >= 2, hence j+n-1 is always greater than zero.

4f95ad8ca2 cmd/preprofile, runtime/coverage: add package comment
As https://go.dev/doc/comment#package says, every package
should have a package comment. Command cmd/preprofile had
one, it was just not being recognized due to a blank line.

For #51430.
For #58102.

d79e6bec63 cmd/go: populate build info for test mains
Before this change, test binaries didn't have build info populated on them
unless they were tests for package main. Now we generate them for all
test binaries so that they can be inspected like other binaries.

We don't need to add the default GODEBUG in printLinkerConfig because it
will now always be present on the build info, and when build info is
present we use it to generate the hash.

Fixes #33976
