6584fe8195 cmd/dist: don't copy files ending in ~ to bootstrap directory
They are editor backup files. They are ignored by .gitignore,
so they can never be real files in the Go repo.

2064413b54 reflect: restore ifaceIndir function for now
CL 583755 removed all uses of the ifaceIndir function,
and the function itself. Unfortunately, ifaceIndir is accessed
using go:linkname by the popular github.com/goccy/go-json package.
A bug has been filed to fix this upstream:
https://github.com/goccy/go-json/issues/506
Until that bug is fixed and the fix is distributed,
keep this function available.
With luck we can remove this in the 1.24 release.

Temporarily mark the function runtime.throw as "go:noinline" for the
time being to work around problems introduced by CL 581215. We do not
ordinarily inline runtime.throw unless the build is beind done with an
elevated inline budget (e.g. "-gcflags=-l=4"), so this change should
only have an effect for those special builds.

dd6dee48b2 net/http: remove misleading response headers on error
This is a reapply of CL 544019 and CL 569815, but with
less aggressive semantics as discussed in proposal #66343.

Error deletes Content-Encoding, since it is writing the response
and any preset encoding may not be correct.

On the error-serving path in ServeContent/ServeFile/ServeFS,
these functions delete additional headers: Etag, Last-Modified,
and Cache-Control. The caller may have set these intending
them for the success response, and they may well not be correct
for error responses.

Fixes #50905.
Fixes #66343.

483a913a55 cmd/compile: add support for telemetry
Add cmd/internal/telemetry to cmd/dist's bootstrapDirs so it's built
when bootstrapping the compiler. cmd/internal/telemetry is a wrapper
arount telemetry functions that stubs out the functions when built in
bootstrap mode to avoid dependencies on x/telemetry in bootstrap mode.

Call telemetry.Start with an empty config to open the counter file, and
increment a counter for when the command is invoked.

After flags are parsed, increment a counter for each of the names of the
flags that were passed in. The counter names will be compile/flag:<name>
so for example we'll have compile/flag:e and compile/flag:E.

In FatalfAt, increment a stack counter for internal errors.

805f6b3f5d cmd/dist: reject accidental use of internal packages from bootstrap toolchain
The compiler was accidentally using internal/godebug from
the Go 1.20 bootstrap toolchain and didn't get the behavior
it expected. Generalizing, we should never assume we know
the behavior of an internal package from an earlier bootstrap
toolchain, so disallow that case in cmd/dist.

acda0107ba cmd/compile: stop using internal/godebug
The main reason not to use internal/godebug is that
people often set GODEBUGs to change the behavior
of the programs they are running with 'go run' or 'go test'.
We don't want the compiler to behave differently as well
in that case: that's too many changes.

Using internal/godebug also breaks bootstrapping
with toolchains that don't have it, or future toolchains
that have a different API in that package.

4513f1a1c1 internal/trace/v2: correctly handle a broken spilled batch
Currently if the first batch of the next generation in the trace is
broken, then the previous generation will fail to parse. The parser
currently relies on one complete batch of the next generation to
continue.

However, this means that recovering a complete generation from a trace
with a broken tail doesn't always work. Luckily, this is fixable. When
the parser encounters an error reading a batch in a generation, it
simply writes down that error and processes it later, once the
generation has been handled. If it turns out the error was for the same
generation and something bigger is broken, then the parser will catch
that sooner when validating the generation's events and the error will
never show up. Otherwise, the generation will parse through successfully
and we'll emit the error once that's done.

Fixes #55160.

ff743ce862 iter: detect and reject double next and double yield in Pull, Pull2
Currently it's possible for next and yield to be called out of sequence,
which will result in surprising behavior due to the implementation.
Because we blindly coroswitch between goroutines, calling next from the
iterator, or yield from the calling goroutine, will actually switch back
to the other goroutine. In the case of next, we'll switch back with a
stale (or zero) value: the results are basically garbage. In the case of
yield, we're switching back to the *same* goroutine, which will crash in
the runtime.

This change adds a single bool to ensure that next and yield are always
called in sequence. That is, every next must always be paired with a
yield before continuing. This restricts what can be done with Pull, but
prevents observing some truly strange behaviors that the user of Pull
likely did not intend, or can't easily predict.

36d32f68f4 runtime: update large object stats before freeSpan in sweep
Currently freeSpan is called before large object stats are updated when
sweeping large objects. This means heapStats.inHeap might get subtracted
before the large object is added to the largeFree field. The end result
is that the /memory/classes/heap/unused:bytes metric, which subtracts
live objects (alloc-free) from inHeap may overflow.

Fix this by always updating the large object stats before calling
freeSpan.

Fixes #67019.

724bab1505 runtime: add traceallocfree GODEBUG for alloc/free events in traces
This change adds expensive alloc/free events to traces, guarded by a
GODEBUG that can be set at run time by mutating the GODEBUG environment
variable. This supersedes the alloc/free trace deleted in a previous CL.

There are two parts to this CL.

The first part is adding a mechanism for exposing experimental events
through the tracer and trace parser. This boils down to a new
ExperimentalEvent event type in the parser API which simply reveals the
raw event data for the event. Each experimental event can also be
associated with "experimental data" which is associated with a
particular generation. This experimental data is just exposed as a bag
of bytes that supplements the experimental events.

In the runtime, this CL organizes experimental events by experiment.
An experiment is defined by a set of experimental events and a single
special batch type. Batches of this special type are exposed through the
parser's API as the aforementioned "experimental data".

The second part of this CL is defining the AllocFree experiment, which
defines 9 new experimental events covering heap object alloc/frees, span
alloc/frees, and goroutine stack alloc/frees. It also generates special
batches that contain a type table: a mapping of IDs to type information.

4ed358b57e go/types, types: represent any using Alias
When GODEBUG=gotypesalias=1 is set, use an actual Alias type to
represent any, rather than a legacy alias representation. This makes any
consistent with other interface aliases, and will eventually make
obsolete the various workarounds for formatting any as 'any' rather than
'interface{}'.

Since any is a global in the Universe scope, we must hijack Scope.Lookup
to select the correct representation. Of course, this also means that we
can't support type checking concurrently while mutating gotypesalias
(or, in the case of types2, Config.EnableAlias). Some care is taken to
ensure that the type checker panics in the event of this type of misuse.

For now, we must still support the legacy representation of any, and the
existing workarounds that look for a distinguished any pointer. This is
done by ensuring that both representations have the same underlying
pointer, and by updating workarounds to consider Underlying.

Fixes golang/go#66921
