The darwin arm64 port was added in Go 1.16 and is a first-class port,
so it should be tracked by cmd/api. This CL does that, backfilling
API files as needed.
It also removes a spurious cgo.Incomplete API feature.

Deprecating an API creates notices that go out to potentially
millions of Go developers encouraging them to update their code.
The choice to deprecate an API is as important as the choice to
add a new API. We should track those and make them explicit.
This will also ensure that deprecations go through proposal review.

Previously, we were using internal/goroot.PkgfileMap to locate
cached export data. However, PkgfileMap regenerates export data
for the entire standard library, whereas gcimporter may only need
a single package.
Under the new approach, we load the export data (still using
'go list -export') for each GOROOT package individually, avoiding work
to rebuild export data for packages that are not needed.
This is a tradeoff: if most packages in GOROOT are actually needed, we
end up making many more calls to 'go list', and may build packages
sequentially instead of in parallel (but with lower latency to start
using the export data from the earlier packages).
On my workstation, starting from a clean cache for each run,
this reduces the wall time of
'go test go/internal/gcimporter -run=TestImportedTypes'
from 22s real time (2m10s user time) to 6s real (27s user),
and only increases 'go test go/internal/gcimporter' from
28s real (2m16s user) to 30s real (2m19s user).

Now that .a files are no longer being placed there, the test is a
noop. Fix this by using go list std (and filtering out testonly
packages) and trying to import all of those to recreate what the test
intended to do.

depending on the Go -lang version.
It also renames the flag types2.Config.AltComparableSemantics to
types2.Config.OldComparableSemantics and inverts its meaning
(or types.Config.oldComparableSemantics respectively).
Add new predicate Satisfies (matching the predicate Implements but
for constraint satisfaction), per the proposal description.
Adjust some existing tests by setting -oldComparableSemantics
and add some new tests that verify version-dependent behavior.
The compiler flag -oldcomparable may be used to temporarily

In CL 449955 we made reading of directories with associated file data
an error, since it is a "must not" in the zip specification. It turns
out that a number of implementations make the mistake of not setting
the correct compression method on directories (in particular the Java
jar tool does this when storing the META-INF directory). If the
compression method used is not 0 (stored) then the compressed size of
the directory can be > 0, despite the uncompressed size still being 0.
Since this mistake is not uncommon, we are forced to tolerate it. We
still fail if the recorded uncompressed size is > 0, which should be
a significantly harder mistake to make.

CL 353849 removed validation of signature parameters being passed to
Verify which led to two distinct problems. If passed a R or S == 0,
encodeSignature would panic since it expects them to be non-zero.
encodeSignature would also normalize (i.e. make non-negative) parameters
by zero padding them, which would result in a signature being passed to
VerifyASN1 which did not match the input signature, resulting in success
in cases where it should've failed. This change re-adds the verification
that 0 < r,s < N before calling ecnodeSignature.
This was caught because tink runs the wycheproof ECDSA vectors against
Verify, where we only run the vectors against VerifyASN1. We should be
doing both.

Which gets rewritten to a conditional move:

Unfortunately, we can't compute &q.f before we've checked if q is nil,
because if it is nil, &q.f is an invalid pointer (if f's offset is
nonzero but small).
Normally this is not a problem because the tmp variable above
immediately dies, and is thus not live across any safepoint. However,
if later there is another &q.f computation, those two computations are
CSEd, causing tmp to be used at both use points. That will extend
tmp's lifetime, possibly across a call.

No one ever runs 'go tool api', because the invocation
has gotten unwieldy enough that it's not practical.
And we don't support it as a standalone tool for other
packages - it's not even in the distribution.
Making it an ordinary package test lets us invoke it
more easily from cmd/dist (as go test cmd/api -check)
and avoids the increasingly baroque code in run.go to
build a command line.
Left in cmd/api even though it's no longer a command
because (1) it uses a package from cmd/vendor and

All mips variant perform syscalls similarly. R2 (v0) holds r1 and R3
(v1) holds r2 of a syscall. The latter is only used by 2-ret syscalls.
A 1-ret syscall would not touch R3 but keeps it as is, making r2 be a
random value. Always reset it to 0 before SYSCALL to fix the issue.
