I got tired of spurious 'git' diffs while a 'go test' was running, so
I fixed the test that produced the diffs. (We need to do that anyway
in order to run them in the module cache, plus it's just good hygiene
not to have tests interfering with each other's sources.)
Tested using:
$ chmod -R ugo-w . && go test ./...; chmod -R u+w .

This CL is based on the work and discussion in CL 24969 and CL 32392.
It simplifies the code further and makes trybots pass on Windows.
Also update the documentation and implementation of the subpackages
function slightly to make it more clear what it's doing.
Background
CL 24943 has made progress on fixing rename.Move behavior on Windows,
but hadn't re-enabled TestMoves at the time. CL 24969 attempted to do
so, but the tests weren't passing and it didn't get merged at the time.
Since that time, CL 65672 has fixed a bug in the subpackages function.
As a result, it's possible to simplify code in Move now.
The subpackages function returns a set of packages in the given srcDir
whose import path equals to root or has "root/" as the prefix.
After CL 65672, it correctly filters out ones that are not true
sub-packages of root. That's why it's not necessary to try to append
a trailing separator when doing the string replacement in Move now.
Given subpackages reports their import paths (always '/'-separated),
not filesystem paths, it's not necessary to use filepath.ToSlash either.

Because go/types is slightly more strict than gc about certain "soft"

I felt the burn of my laptop on my legs, spinning away while processing
goimports, and felt that it was time to make goimports great again.
Over the past few years goimports fell into a slow state of disrepair
with too many feature additions and no attention to the performance
death by a thousand cuts. This was particularly terrible on OS X with
its lackluster filesystem buffering.
This CL makes goimports stronger, together with various optimizations
and more visibility into what goimports is doing.
* adds more internal documentation
* avoids scanning $GOPATH for answers when running goimports on a file
under $GOROOT (for Go core hackers)
* don't read all $GOROOT & $GOPATH directories' Go code looking for
their package names until much later. Require the package name of
missing imports to be present in the last two directory path
components. Then only try importing them in order from best to
worst (shortest to longest, as before), so we can stop early.
* when adding imports, add names to imports when the imported package name
doesn't match the baes of its import path. For example:
import foo "example.net/foo/v1"
* don't read all *.go files in a package directory once the first file
in a directory has revealed itself to be a package we're not looking
for. For example, if we're looking for the right "client" for "client.Foo",
we used to consider a directory "bar/client" as a candidate and read
all 50 of its *.go files instead of stopping after its first *.go
file had a "package main" line.
* add some fast paths to remove allocations
* add some fast paths to remove disk I/O when looking up the base
package name of a standard library import (of existing imports in a
file, which are very common)
* adds a special case for import "C", to avoid some disk I/O.
* add a -verbose flag to goimports for debugging
On my Mac laptop with a huge $GOPATH, with a test file like:
package foo
import (
"fmt"
"net/http"
)
/*
*/
import "C"
var _ = cloudbilling.New
var _ = http.NewRequest
var _ = client.New
... this took like 10 seconds before, and now 1.3 seconds. (Still
slow; disk-based caching can come later)
