… a builtin type

In CL 536715 we're changing the gofrontend export data to report
"any" as a builtin type. This permits us to distinguish the builtin
type from some other package-level type "any". That requires an update
to this code.

Fixes #67849

…tractions dependency

Previously, go would not report retractions of dependencies that have a
newer version of Go. With this change, we will still display retractions despite a version difference when go list -u -m is used.

… of data segment

Currently the runtime.end symbol is put into the noptrbss section,
which is usually the last section, except that when fuzzing is
enabled, the last section is actually .go.fuzzcntrs. The
runtime.end symbol has the value pointing to the end of the data
segment, so if it is not in the last section, the value will not
actually be in the range of the section. This causes an assertion
failure in the new Apple linker. This CL fixes this by putting it
in the last section.

Updates #65169.
Fixes #67944.

…TO tests on the builders

For whatever reason, on the builders, when using /usr/bin/ld (the
default linker) with -flto we end up with problems. Specifically, the
linker seems to require LLVMgold.so and can't find it. I'm not really
sure why, but what definitely seems to work is forcing use of lld, which
ships with our clang installation on the builders.

Just enforce this on the builders for now; I've actually had very few
problems running this locally (and I think I'm also mixing and matching
linkers and toolchains too...), so it may be related to the version of
clang we're testing with.

For #67698.
For #67714.

…fuzzer tests all short

CL 589295 only made one of the two tests short, because the other one
seemed to be passing consistently in short mode. On the builders, it
seems to still fail maybe 30% of the time by taking too long. Disable
these tests in short mode.

This CL was merged with CL 589295 before cherry-picking.

…lback

callbackUpdateSystemStack contains a fast path to exit early without
update if SP is already within the g0.stack bounds.

This is not safe, as a subsequent call may have new stack bounds that
only partially overlap the old stack bounds. In this case it is possible
to see an SP that is in the old stack bounds, but very close to the
bottom of the bounds due to the partial overlap. In that case we're very
likely to "run out" of space on the system stack.

We only need to do this on extra Ms, as normal Ms have precise bounds
defined when we allocated the stack.

TSAN annotations are added to x_cgo_getstackbounds because bounds is a
pointer into the Go stack. The stack can be reused when an old thread
exits and a new thread starts, but TSAN can't see the synchronization
there. This isn't a new case, but we are now calling more often.

For #62440.
Fixes #67297.

…pect-100-continue requests

When sending a request with an "Expect: 100-continue" header,
we must send the request body before sending any further requests
on the connection.

When receiving a non-1xx response to an "Expect: 100-continue" request,
send the request body if the connection isn't being closed after
processing the response. In other words, if either the request
or response contains a "Connection: close" header, then skip sending
the request body (because the connection will not be used for
further requests), but otherwise send it.

Correct a comment on the server-side Expect: 100-continue handling
that implied sending the request body is optional. It isn't.
