gcBgMarkStartWorkers currently starts workers one at a time, using a
note to communicate readiness back from the worker.
However, this is a pretty standard goroutine, so we can just use a
channel to communicate between the goroutines.
In addition to being conceptually simpler, using channels has the
additional advantage of coordinating with the scheduler. Notes use OS
locks and sleep the entire thread, requiring other threads to run the
other goroutines. Waiting on a channel allows the scheduler to directly
run another goroutine. When the worker sends to the channel, the
scheduler can use runnext to run gcBgMarkStartWorker immediately,
reducing latency.
We could additionally batch start all workers and then wait only once,
however this would defeate runnext switching between the workers and
gcBgMarkStartWorkers, so in a heavily loaded system, we expect the
direct switches to reduce latency.

Rather than implementing a new, less complete mechanism to check
if a selector exists with different capitalization, use the
existing mechanism in lookupFieldOrMethodImpl by making it
available for internal use.
Pass foldCase parameter all the way trough to Object.sameId and
thus make it consistently available where Object.sameId is used.
From sameId, factor out samePkg functionality into stand-alone
predicate.
Do better case distinction when reporting an error for an undefined

CL 514596 adds float min/max for amd64, this CL adds it for riscv64.
The behavior of the RISC-V FMIN/FMAX instructions almost match Go's
requirements.
However according to RISCV spec 8.3 "NaN Generation and Propagation"
>> if at least one input is a signaling NaN, or if both inputs are quiet
>> NaNs, the result is the canonical NaN. If one operand is a quiet NaN
>> and the other is not a NaN, the result is the non-NaN operand.
Go using quiet NaN as NaN and according to Go spec

This requires the float min/max implementation to check whether one
of operand is qNaN before float mix/max actually execute.
This CL also fix a typo in minmax test.

testenv's TestHasGoBuild test is supposed to allow noopt builders to not
have go build, but the pattern match is failing on the LUCI builders
where a test shard might have an additional "-test_only" suffix in the
builder name. Furthermore, in the LUCI world, "run mods" (the builder
type suffixes) are supposed to be well-defined and composable, so it
doesn't make sense to restrict "-noopt" to the builder suffix anyway.
This change modifies the test to allow "-noopt" to appear anywhere in
the builder name when checking if it's running on a noopt builder.

On Windows, the netpoll is currently coupled with the websocket usage

This CL moves the websocket handling out of the runtime and puts it into

This is a good refactor per se, as the Go runtime shouldn't know about

load ws2_32.dll when the Go program actually uses websockets.

Earlier in the development of the new tracer, m.id was used as a the
canonical ID for threads. Later, we switched to m.procid because it
matches the underlying OS resource. However, in that switch, we missed a
spot.
The tracer catches and emits statuses for goroutines that have remained
in either waiting or syscall across a whole generation, and emits a
thread ID for the latter set. The ID being used here, however, was m.id
instead of m.procid, like the rest of the tracer.
This CL also adds a regression test. In order to make the regression
test actually catch the failure, we also have to make the parser a
little less lenient about GoStatus events with GoSyscall: if this isn't
the first generation, then we should've seen the goroutine bound to an
M already when its status is getting emitted for its context. If we emit
the wrong ID, then we'll catch the issue when we emit the right ID when
the goroutine exits the syscall.
Fixes#65196.

The pgo compilation time is very long if the profile file is large.
We added a preprocess tool to pre-parse profile file in order to
expedite the compile time.
