This change tweaks and simplifies the descriptions of a couple metrics
to make them easier to parse (for humans).

d902791b50 sync: use 386 instead of x86-32 to refer to the 32 bit x86 architecture
This aligns the naming with GOARCH using 386 as a build target for
this architecture and makes it more easily found when searching
for documentation related to the build target.

f7342596da syscall: add DLLError.Unwrap function
Because we're expecting for future functions to be unavailable, we
should add an Unwrap() function to the DLLError struct, so that people
can test for this situation easily via:

    if errors.Is(err, syscall.ERROR_PROC_NOT_FOUND) { ... }

DLLError already was wrapping the underlying Errno error, but never got
the Go 1.13 helper method.

Fixes golang/go#42584

f93ef07b11 cmd/go/internal/modload: remove the Reqs function
The Reqs function returns an mvs.Reqs implemention for the global
build list. The API that it presents assumes that the build list is
globally consistent (problematic for #40775) and readily available
(problematic for #36460).

Fortunately, it is no longer used outside of the modload package.
We can instead use individual instances of the unexported mvsReqs
struct, making the dependency on the global build list more explicit.

For #40775

would succeed later when offline. However, 'go list -m all' may
already fail when offline after 'go mod tidy', so it doesn't make
sense to add complexity to 'go get'.

Instead, remove the ListModules call and fix the test that
accidentally depended on it.

7eed73f36f go/types, go/constant: handle infinities as unknown values
With this change, constant literals (and results of constant
operations) that internally become infinities are represented
externally (to go/constant) as "unknown" values.

The language has no provisions to deal with infinite constants,
and producing unknown values allows the typechecker to report
errors and avoid invalid operations (such as multiplication of
zero with infinity).

Fixes #20583.

cb674b5c13 cmd/compile,cmd/asm: fix function pointer call perf regression on ppc64
by inserting hint when using bclrl.

Using this instruction as subroutine call is not the expected
default behavior, and as a result confuses the branch predictor.

The default expected behavior is a conditional return from a
subroutine.

We can change this assumption by encoding a hint this is not a
subroutine return.

The regex benchmarks are a pretty good example of how much this
hint can help generic ppc64le code on a power9 machine:

c31540364c cmd/compile: flag "-d=dumpptrs" to print Node ptrs in Dump output
The printing of the ptr values can mean that two dump outputs can't easily be
compared for the identical structure, so adding the "-d=dumpptrs" option to make
printing of Node pointer values be an option.

4d048194cd runtime: support new callbackasm1 calling convention on windows/arm
This updates the callbacks implementation on windows/arm for the
changes made in CL 258938. At the time, that was left as a TODO.

At the same time, it also extends the previous support for only 4
arguments to also support additional arguments on the stack. This is
required for functions like SetWinEventHook, which take 7 arguments. It
does this by pushing r0-r3 onto the stack before the normal prologue,
and then pointing the args struct to that location.

This is derived from CL 270077 and CL 270078.

Updates #40724.
Fixes #42591.

5ba1c3f290 cmd/go/internal/modload: remove SetBuildList
For the last remaining call site (in cmd/go/internal/work, added for
the new 'go install pkg@version' codepath in CL 254365), use
EditBuildList instead.

SetBuildList assumes that the caller has enough information to produce
a complete, coherent build list. With lazy loading, producing a
complete, coherent build list is no longer quite so trivial.

In CL 263267, I rewrote the main caller of SetBuildList (the 'go get'
command), and in the process added a more targeted modload hook
(EditBuildList). That hook also suffices for 'go install pkg@version'.
The resulting error messages are perhaps not as smooth as they ought
to be, but if they are too awkward we should probably fix them for
'go get' too, and the commands can continue to share the edit hook.

Updates #40276

ff2824d4b3 cmd/go/internal/modcmd: eliminate a call to modload.LoadedModules
modload.LoadedModules reveals more information than necessary about
whether modules have been loaded lazily. The 'vendor' subcommand
doesn't actually need that much information: it has all of the
information that it needs from prior calls to LoadPackages and
ModFile.

Currently storing keys that contain unsafe.
Pointer in a map could result inruntime panic when printing the map.
The root cause is that unsafe.Pointer is not comparable.

35693d037f cmd/compile: fix miscompilation during inlining
When inlining a function call expression, it's possible that the
function callee subexpression has side effects that need to be
preserved. This used to not be an issue, because inlining wouldn't
recognize these as inlinable anyway. But golang.org/cl/266199 extended
the inlining logic to recognize more cases, but did not notice that
the actual inlining code was discarding side effects.

Issue identified by danscales@.

Fixes #42703.

5b0ec1a6ac cmd/compile: fix panic in field tracking logic
Within the frontend, we generally don't guarantee uniqueness of
anonymous types. For example, each struct type literal gets
represented by its own types.Type instance.

However, the field tracking code was using the struct type as a map
key. This broke in golang.org/cl/256457, because that CL started
changing the inlined parameter variables from using the types.Type of
the declared parameter to that of the call site argument. These are
always identical types (e.g., types.Identical would report true), but
they can be different pointer values, causing the map lookup to fail.

The easiest fix is to simply get rid of the map and instead use
Node.Opt for tracking the types.Field. To mitigate against more latent
field tracking failures (e.g., if any other code were to start trying
to use Opt on ODOT/ODOTPTR fields), we store this field
unconditionally. I also expect having the types.Field will be useful
to other frontend code in the future.

Finally, to make it easier to test field tracking without having to
run make.bash with GOEXPERIMENT=fieldtrack, this commit adds a
-d=fieldtrack flag as an alternative way to enable field tracking
within the compiler. See also #42681.

Fixes #42686.

b4f3d52f6a sync: document RWMutex race semantics
RWMutex provides explicit acquire/release synchronization events to the
race detector to model the mutex. It disables sync events within the
methods to avoid e.g., the atomics from adding false synchronization
events, which could cause false negatives in the race detector.

b63db7f724 runtime: give test child time to block
The child in TestPanicSystemstack prints "x\n" and then blocks on a
lock. Receiving those bytes only indicates that the child is _about to
block_. Since we don't have a way to know when it is fully blocked,
sleep a bit to give it time to block. This makes us less likely to lose
the race and signal before the child blocks, which will fail the test as
the stack trace cannot be read from a running G.

0:

|<---------- buf ----------->|<-heap->|

041a4e4c34 go/types: add test case for incorrect map index expression
The existing code for map index expressions checked the
wrong variable (x rather than key) to see if the index
assignment was correct. Since x.mode was always valid in
that case, type-checking didn't follow the error exit in
case of an incorrect map index expression.

However, since we know the correct map element type
irrespective of the validity of the map key, the existing
code path is preferrable over exiting early via an error
because the map index expression returns a valid type which
then can be used for further type-checking.

Removed the unneeded 'if' statement and added a test case
producing the expected two errors (rather than only one if
we would "correct" the 'if' statement instead).

In summary, this commit adds a test but doesn't change the
behavior of type-checking of map index expressions.
