CL 276272 accidentally skipped everything in TestStdlib while trying to
skip nested submodules of std and cmd.
For now, narrow the skip to just the problematic submodule rather than
trying to generalize. We can re-evaluate if it becomes a pattern to
vendor submodules in this way.
Fixes #46027

This change replaces the crypto/ed25519/internal/edwards25519 package
with code from filippo.io/edwards25519, a significantly faster, safer,
well tested (over 1600 lines of new tests, 99% test coverage), and
better documented (600 lines of new comments) implementation.
Some highlights:
* an unsaturated 51-bit limb field implementation optimized for 64-bit
architectures and math/bits.Mul64 intrinsics
* more efficient variable time scalar multiplication using multi-width
non-adjacent form with a larger lookup table for fixed-base
* a safe math/big.Int-like API for the Scalar, Point, and field.Element
types with fully abstracted reduction invariants
* a test suite including a testing/quick fuzzer that explores edge case
values that would be impossible to hit randomly, and systematic tests
for arguments and receiver aliasing
* point decoding rules that strictly match the original logic of
crypto/ed25519/internal/edwards25519, to avoid consensus issues
* AssemblyPolicy-compliant assembly cores for arm64 and amd64, the
former under 20 lines, and the latter generated by a program based on
github.com/mmcloughlin/avo that can be reviewed line-by-line against
the generic implementation

The code in this CL is a copy of the filippo.io/edwards25519 module at
version v1.0.0-beta.3.0.20210405211453-c6be47d67779 with only the
following functions removed as irrelevant to crypto/ed25519:
- (*Point).BytesMontgomery()
- (*Point).MultByCofactor()
- (*Scalar).Invert()
- (*Point).MultiScalarMult()
- (*Point).VarTimeMultiScalarMult()
This codebase took a long journey outside the standard library before
making its way back here. Its oldest parts started as a faster field
implementation rewrite by George Tankersley almost four years ago,
eventually submitted as CL 71950 but never merged. That code was then
merged into github.com/gtank/ristretto255, which also started as an
internal/edwards25519 fork. There it was worked on by me, George, and
Henry de Valence as a backend for our Go ristretto255 implementation.
Finally, I extracted the edwards25519 code into a reusable package as
filippo.io/edwards25519.
Now, we're ready for the standard library to become the source of truth
for this code again, while filippo.io/edwards25519 will become a
re-packaged and extended version for external use, since we don't want
to expose unsafe curve operations in x/crypto or the standard library.

Named.SetTParams sets the type parameters for a named type.
Named.Orig returns the original generic type an instantiated
type is derived from. Added a new field orig for that purpose
and renamed the already existing orig field to fromRHS.

The changes between (equivalent, and reviewed) go/types/stdlib_test.go
and stdlib_test.go can be seen by comparing patchset 1 and 2. The actual
changes are removing the "// UNREVIEWED" marker, using the os package
instead of ioutil, and some comment adjustments. Also, bug251.go passes
because of recent changes.
The primary difference is in the firstComment function which
doesn't have access to a scanner and instead uses the syntax
package's CommentsDu function.

This change replaces methods with functions to reduce the API surface of

version checking
Add the Config.Lang field which may be set to a Go version string,
such as "go1.12". This is a string rather than explicit semantic
version numbers (such as {1, 12}) for API robustness; a string
is more flexible should we need more or different information.
Add -lang flag to types2 package for use with (manual) testing
when running "go test -run Check$ -lang=... -files=...".
While changing flags, look for comma-separated (rather than space-
separated) files when providing the -file flag.
Check that numeric constant literals, signed shift counts are
accepted according to the selected language version.
Type alias declarations and overlapping embedded interfaces are
not yet checked.

arithmetic overflow
Factor out the existing "constant representation" check after
untyped constant arithmetic and combine with an overflow check.
Use a better heuristic for determining the error position if we
know the error is for a constant operand that is the result of an
arithmetic expression.
Related cleanups.
With this change, untyped constant arithmetic reports an error
when (integer) constants become too large (> 2048 bits). Before,
such arithmetic was only limited by space and time.

As with CL 285875, this required resolving some conflicts around
handling of //go:embed directives. Still further work is needed to
reject uses of //go:embed in files that don't import "embed", so this
is left as a TODO. (When this code was written for dev.typeparams, we
were still leaning towards not requiring the "embed" import.)
Also, the recent support for inlining closures (CL 283112) interacts
poorly with -G=3 mode. There are some known issues with this code
already (#43818), so for now this CL disables inlining of closures
when in -G=3 mode with a TODO to revisit this once closure inlining is
working fully.

CL 279531 disabled these because they were causing
trouble with the automation for the big move.
The big move is over. Reenable them.

This is making rf unhappy for extremely subtle reasons,
so for now just disable the external test here. Will reenable
once the big rewrite is done.

On top of the merge, the following fixes were applied:
+ Debug["G"] changed to Debug.G, following golang.org/cl/263539.
+ issue42058a.go and issue42058b.go were skipped in
types2/stdlib_test.go. go/types does not produce errors related to
channel element size.

types2 and importer
This is a copy of the importer and types2 (unreviewed) prototype version
excluding the testdata directory containing tests (see below). Each file
is marked with the comment
// UNREVIEWED
on the first line. The plan is to check in this code wholesale (it runs and
passes all tests) and then review the code file-by-file via subsequent CLs
and remove the "// UNREVIEWED" comments as we review the files.
Since most tests are unchanged from the original go/types, the next CL will
commit those tests as they don't need to be reviewed again. (Eventually we
may want to factor them out and share them from a single place, e.g. the
test directory.)
The existing file fmtmap_test.go was updated.
