In CL 258220 I added replacement versions to the repo versions used in
the modload.Query functions. The versions are computed from a map in
the modfile index, which has a nondeterministic iteration order.
I added a short-circuit condition to skip sorting in the (vastly
common) case where no replacement versions are added. However, while
cleaning up the change I accidentally deleted the line of code that
sets that condition. As a result, the test of that functionality
(mod_get_replaced) has been failing nondeterministically.
This change fixes the condition by comparing the slices before and
after adding versions, rather than by setting a separate variable.
The test now passes reliably (tested with -count=200).

This change removes that assumption, instead adding a callback

On 386 and arm, unaligned 64-bit atomics aren't safe, so we check for
this and panic. Currently, we panic by dereferencing nil, which may be
expedient but is pretty user-hostile since it gives no hint of what
the actual problem was.
This CL replaces this with an actual panic. The only subtlety here is
now the atomic assembly implementations are calling back into Go, so
they have to play nicely with stack maps and stack scanning. On 386,
this just requires declaring NO_LOCAL_POINTERS. On arm, this is
somewhat more complicated: first, we have to move the alignment check
into the functions that have Go signatures. Then we have to support
both the tail call from these functions to the underlying
implementation (which requires that they have no frame) and the call
into Go to panic (which requires that they have a frame). We resolve
this by forcing them to have no frame and setting up the frame
manually just before the panic call.

We already allow inlining "if" and "goto" statements, so we might as
well allow "for" loops too. The majority of frontend support is
already there too.
The critical missing feature at the moment is that inlining doesn't
properly reassociate OLABEL nodes with their control statement (e.g.,
OFOR) after inlining. This eventually causes SSA construction to fail.
As a workaround, this CL only enables inlining for unlabeled "for"
loops. It's left to a (yet unplanned) future CL to add support for
labeled "for" loops.
The increased opportunity for inlining leads to a small growth in
binary size. For example:

debugCachedWork and all of its dependent fields and code were added to
aid in debugging issue #27993. Now that the source of the problem is
known and mitigated (via the extra work check after STW in gcMarkDone),
these extra checks are no longer required and simply make the code more
difficult to follow.
Remove it all.

Currently, there are several panics in token that simply say "illegal!". This CL
adds the values.
This is valuable when the token call is wrapped under several layers and you
can't easily see which value is being passed to token.

Per @mdempsky's suggestion: Instead of representing a type instantiation T[P]
by an IndexExpr node, and a type instantiation with multiple type arguments
T[P1, P2] by a CallExpr node with special Brackets flag, always use an IndexExpr.
Use a ListExpr as index in the (less common) case of multiple type arguments.
This removes the need for the CallExpr.Brackets field and cleans up the parser
code around type instantiations.
Backport of syntax package changes from https://golang.org/cl/262020.

Add support of internal linking on darwin/arm64 (macOS).
Still incomplete. Pure Go binaries work. Cgo doesn't. TLS is not
set up when cgo is not used (as before) (so asynchronous
preemption is not enabled).
Internal linking is not enabled by default but can be requested
via -ldflags=-linkmode=internal.
Updates #38485.

This changes checks the signature generated during CreateCertificate
and returns an error if the verification fails. A benchmark is also
added. For RSA keys the delta looks to be insignificant, but for
ECDSA keys it introduces a much larger delta which is not ideal.
