When unmarshaling to a map, the map's key type must either be a string,

defined type, reflect.Kind will not distinguish between the static type
and the underlying type. In:
var x MyString = "x"
t := reflect.TypeOf(x)
println(t.Kind() == reflect.String)
the Kind of x is still reflect.String, even though the static type of x
is MyString.
Moreover, checking for the map's key type is a string occurs first, so
even if the map key type MyString implements encoding.TextUnmarshaler,
it will be ignored.
To fix the bug, check for encoding.TextUnmarshaler first.

When in module mode outside of any module, 'go build' and most other
commands will now report an error instead of resolving a package path
to a module.
Previously, most commands would attempt to find the latest version of
a module providing the package. This could be very slow if many
packages needed to be resolved this way. Since there is no go.mod file
where module requirements can be saved, it's a repeatedly slow and
confusing experience.
After this change, 'go build' and other commands may still be used
outside of a module on packages in std and source files (.go
arguments) that only import packages in std. Listing any other package
on the command line or importing a package outside std will cause an
error.
'go get' is exempted from the new behavior, since it's expected that
'go get' resolves paths to modules at new versions.

This change introduces a new interface, load.ImportPathError. An error
may satisfy this by providing an ImportPath method and including the
import path in its error text. modload.ImportMissingError satisfies
this interface. load.ImportErrorf also provides a convenient way to
create an error satisfying this interface with an arbitrary message.
When load.PackageError formats its error text, it may omit the last
path on the import stack if the wrapped error satisfies
ImportPathError and has a matching path.
To make this work, PackageError.Err is now an error instead of a
string. PackageError.MarshalJSON will write Err as a string for
'go list -json' output.
When go/build.Import invokes 'go list' in module mode, it now runs
with '-e' and includes '.Error' in the output format instead of
expecting the error to be in the raw stderr text. If a package error
is printed and a directory was not found, the error will be returned
without extra decoration.

When rewriting a go.mod file, we currently sort all of the require
lines in a block. The way the parser works is that it considers
preceding blank lines to be empty comment lines, and preceding empty
comment lines are "owned" by their adjoining line. So when we go to sort
them, the empty lines follow around each sorted entry, which doesn't
make a whole lot of sense, since usually vertical space is inserted to
show sections, and if things get moved around by sorting, those sections
are no longer meaningful. This all results in one especially troublesome
edge case: blank lines between a block opening ("require (") and the
first block line ("golang.org/x/sys ...") are not treated the same way
and are rewritten out of existence.
Here's an example of the behavior this fixes.
Starting input file:
require (
golang.zx2c4.com/wireguard master
golang.org/x/crypto latest
golang.org/x/net latest
golang.org/x/sys latest
golang.org/x/text latest
github.com/lxn/walk latest
github.com/lxn/win latest
)
Now we run this through `GOPROXY=direct go get -d`:
require (
github.com/lxn/walk v0.0.0-20190619151032-86d8802c197a
github.com/lxn/win v0.0.0-20190716185335-d1d36f0e4f48

golang.org/x/sys v0.0.0-20190813064441-fde4db37ae7a

golang.zx2c4.com/wireguard v0.0.20190806-0.20190822065259-3cedc22d7b49
)
Notice how the blank lines before lxn/walk and x/crypto were preserved.
Finally, we have this be rewritten yet again with a call to `go build`:
require (
github.com/lxn/walk v0.0.0-20190619151032-86d8802c197a
github.com/lxn/win v0.0.0-20190716185335-d1d36f0e4f48

golang.org/x/net v0.0.0-20190813141303-74dc4d7220e7
golang.org/x/sys v0.0.0-20190813064441-fde4db37ae7a

golang.zx2c4.com/wireguard v0.0.20190806-0.20190822065259-3cedc22d7b49
)
In this final resting point, the first blank line has been removed.
The discrepancy between those two last stages are especially bothersome,
because it makes for lots of dirty git commits and file contents
bouncing back and forth.
This commit fixes the problem as mentioned above, getting rid of those
preceding blank lines. The output in all cases looks as it should, like
this:

For example, if a test calls os.Exit(0), that could trick a 'go test'
run into not running some of the other tests, and thinking that they all
succeeded. This can easily go unnoticed and cause developers headaches.
Add a simple sanity check as part of 'go test': if the test binary
succeeds and doesn't print anything, we should error, as something
clearly went very wrong.
This is done by inspecting each of the stdout writes from the spawned
process, since we don't want to read the entirety of the output into a
buffer. We need to introduce a "buffered" bool var, as there's now an
io.Writer layer between cmd.Stdout and &buf.
A few TestMain funcs in the standard library needed fixing, as they
returned without printing anything as a means to skip testing the entire
package. For that purpose add testenv.MainMust, which prints a warning
and prints SKIP, similar to when -run matches no tests.
Finally, add tests for both os.Exit(0) and os.Exit(1), both as part of
TestMain and as part of a single test, and test that the various stdout
modes still do the right thing.

The branch-on-count instructions on s390x decrement the input
register and then compare its value to 0. If not equal the branch
is taken.
These instructions are useful for implementing loops with a set
number of iterations (which might be in a register).
For example, this for loop:
for i := 0; i < n; i++ {
... // i is not used or modified in the loop
}
Could be implemented using this assembly:
MOVD Rn, Ri
loop:
...
BRCTG Ri, loop
Note that i will count down from n in the assembly whereas in the
original for loop it counted up to n which is why we can't use i
in the loop.
These instructions will only be used in hand-written codegen and
assembly for now since SSA blocks cannot currently modify values.
We could look into this in the future though.

The element size for VSUMQF and VSUMQG was off by one. Fix this
and add tests for VSUM* instruction encodings.

In CL 197059, I suppressed errors if the target package was already found.
However, that does not cover the case of passing a '/v2' module path to
'go get' when the module does not contain a package at its root.
This CL is a minimal fix for that case, intended to be backportable to 1.13.
(Longer term, I intend to rework the version-validation check to treat
all mismatched paths as ErrNotExist.)

You were a useful port and you've served your purpose.
Thanks for all the play.
A subsequent CL will remove amd64p32 (including assembly files and
toolchain bits) and remaining bits. The amd64p32 removal will be
separated into its own CL in case we want to support the Linux x32 ABI
in the future and want our old amd64p32 support as a starting point.
