Currently if a signal lands on a non-Go thread that's handled by the Go
handler, Go will emit a message. However, unlike everywhere else in the
runtime, Go will not abort the process after, and the signal handler
will try to continue executing.
This leads to cascading failures and possibly even memory corruption.

When the expand_calls phase in the SSA backend lowers prolog OpArg
values into OpArgIntReg/OpArgFloatReg values, we don't always record
the assocation between the new lowered value and the parameter name.
This patch handles the simple case where a given parameter fits into
exactly one register; in this scenario it makes sense to manufacture a
new pseudo-slot for the value that points to the param, and install
the slot/value mapping in the NamedValues table for the function. More
work will be needed to deal with params that span multiple registers;
that will need to be addressed in a subsequent patch.
This change improves the parameter error rate "optargorder" benchmark
by about 7-8% (when run on the optargorder binary).

If we're testing through dist, we're testing the implementation of Go,
so we're interested in any package failing with potential runtime
issues. In these cases, we'd like to have as much relevant detail as
possible, but currently runtime stack frames and goroutines are
suppressed due to the default GOTRACEBACK setting.
So, try to set GOTRACEBACK to system if it's unset. Check if it's unset
first so we don't override the user asking for a lower or higher level.
This change was brought up in the context of #45916, since there's an
apparent deadlock (or something!) in the runtime that appears when
running other code, but it's difficult to see exactly where it's
blocked. However, this change is very generally useful.
This change also runs scripted tests with GOTRACEBACK=system, upgrading
from GOTRACEBACK=all. Often, script tests can trigger failures deep in
the runtime in interesting ways because they start many individual Go
processes, so being able to identify points of interest in the runtime
is quite useful.

Even though x/mod is now lazy, this has no immediate effect on the
size of cmd/go.sum: all of the existing dependencies are still pulled
in via the dependency on x/tools, which is itself not yet lazy (that's
CL 315570).

We were already setting GIT_SSH_COMMAND (if unset) to explicitly
include 'ControlMaster=no' in order to disable connection pooling.
Now we also set 'BatchMode=yes' to suppress password prompts for
password-protected keys.
While we're here, we also set GCM_INTERACTIVE=never to suppress
similar prompts from the Git Credential Manager for Windows.

Lots of constant SSA values we put in the entry block so that
CSE can easily combine them. With -N, however, we don't run CSE, so
putting values in the entry block only serves to extend their lifetime
for no benefit.
Fixes#45897. The number of live SSA values per block goes from >5K to 22.
Memory use goes from ~3GB to ~400MB.

This is part of getting debugging into good shape
with the register ABI. (This may generate a backport
for 1.16, there was some regression there as well.)
This is not necessarily fully-baked yet; my goal is to
make it work "well enough" for actual debugging, then
revisit the metrics, which are currently ignorant
of registers used for passing parameters (currently,
rejects them as a valid option).

The functions SwapPointer and CompareAndSwapPointer can be used to
interact with unsafe.Pointer, however generally it is prefered to work
with Value, due to its safer interface. As such, they have been added
along with glue logic to maintain invariants Value guarantees.
To meet these guarantees, the current implementation duplicates much of
the Store function. Some of this is due to inexperience with concurrency
and desire for correctness, but the lack of generic programming
functionality does not help.

These new methods provide support for cases where performance is a
primary concern. For example, copying files from an existing zip to a
new zip without incurring the decompression and compression overhead.
Using an optimized, external compression method and writing the output
to a zip archive. And compressing file contents in parallel and then
sequentially writing the compressed bytes to a zip archive.

At this time, the golang.org/s/release process arranges such that the
api/go1.n.txt file is created when a Go 1.N Beta 1 release is being cut.
The API check is currently configured so that tests don't fail visibly
even if api/go1.n.txt becomes a subset of the actual API additions in
the upcoming Go 1.N release as long as 'go version' has "devel" in it.
The first time that 'go version' output drops the "devel" substring
during testing is after the release-branch.go1.N branch is created
as part of the process to cut a Go 1.N Release Candidate 1 release.
The month or so between Beta 1 and RC 1 is well into the freeze and
deliberate API changes are rare and very intentional. There seems to
be agreement that it's healthy to make the API check stricter during
that time period. Doing so will ensure that api/go1.n.txt cannot get
stale after creation without anyone noticing, and may catch CLs that
don't have the intended diff on the API.
This CL changes behavior to be simple and clear: from the moment
an api/go1.n.txt file corresponding to the current Go version in
development is added to the tree, silent API additions stop being
permitted.
This CL also moves the magical "override the value of -allow_new flag
if runtime.Version() contains 'devel' string" behavior from cmd/api
command to the run.go script that calls it, making the CLI of cmd/api
itself less surprising.
Fixes#43956.

Even though x/term is now lazy, this has no overall effect (yet) on
the contents of cmd/go.sum, because the dependency that would be
pruned out (an old version of x/sys) is still transitively required
through x/crypto, x/sys, and/or x/tools.
Once those modules are also lazy (CL 316109, CL 316111, and CL 315570
respectively), the extra go.sum entries for x/sys will drop out.
