This CL changes the export data format to preserve alias uses.
Previously they were stripped away with types2.Unalias. For backwards
compatibility, we use pkgbits.TypeNamed, which is already used for the
predeclared aliases byte, rune, and any.
While here, remove unnecessary uses of types2.Unalias, and add a
missing one in recvBase to handle:
type T int
type A = T
func (*A) m() {}

CL 464349 added a new linkname to provide gcount to runtime/pprof to
avoid a STW when estimating the goroutine profile allocation size.
However, adding a linkname here isn't necessary for a few reasons:
1. We already export gcount via NumGoroutines. I completely forgot about
this during review.
2. aktau suggested that goroutineProfileWithLabelsConcurrent return
gcount as a fast path estimate when the input is empty.
The second point keeps the code cleaner overall, so I've done that.

When readying a goroutine, the scheduler typically places the readied
goroutine in pp.runnext, which will typically be the next goroutine to
run in the schedule.
In order to prevent a set of ping-pong goroutines from simply switching
back and forth via runnext and starving the rest of the run queue, a
goroutine scheduled via runnext shares a time slice (pp.schedtick) with
the previous goroutine.
sysmon detects "long-running goroutines", which really means Ps using
the same pp.schedtick for too long, and preempts them to allow the rest
of the run queue to run. Thus this avoids starvation via runnext.
However, wasm has no threads, and thus no sysmon. Without sysmon to
preempt, the possibility for starvation returns. Avoid this by disabling
runnext entirely on wasm. This means that readied goroutines always go
on the end of the run queue and thus cannot starve via runnext.
Note that this CL doesn't do anything about single long-running
goroutines. Without sysmon to preempt them, a single goroutine that
fails to yield will starve the run queue indefinitely.

Error() function accesses the package struct's Dir field, so if we

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.

testenv's TestHasGoBuild test is supposed to allow noopt builders to not

where a test shard might have an additional "-test_only" suffix in the

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
