Trybots started failing on js/wasm after golang.org/cl/175797 landed,
but it seemed completely unrelated. It would fail very consistently on
the heapsampling.go test.
Digging deeper it was very difficult to ascertain what was going wrong,
but clearly m.locks for some m was non-zero when calling into the
scheduler.
The failure comes from the fact that lock calls into gosched, but it's
unclear how exactly we got there in the first place; there should be no
preemption in this single-threaded context.
Furthermore, lock shouldn't be calling gosched_m at all because in a
single-threaded context, the thread shouldn't be preempted until it
actually unlocks.
But, digging further it turns out the implementation in lock_js.go never
incremented or decremented m.locks. This is definitely wrong because
many parts of the runtime depend on that value being set correctly.
So, this change removes the loop which calls into gosched_m (which
should be unnecessary) and increments and decrements m.locks
appropriately. This appears to fix the aforementioned failure.

This change makes it so that during scavenging we split spans when the
span we have next for scavenging is larger than the amount of work we
have left to do.
The purpose of this change is to improve the worst-case behavior of the
scavenger: currently, if the scavenger only has a little bit of work to
do but sees a very large free span, it will scavenge the whole thing,
spending a lot of time to get way ahead of the scavenge pacing for no
reason.
With this change the scavenger should follow the pacing more closely,
but may still over-scavenge by up to a physical huge page since the
splitting behavior avoids breaking up huge pages in free spans.
This change is also the culmination of the scavenging improvements, so
we also include benchmark results for this series (starting from
"runtime: merge all treaps into one implementation" until this patch).
This patch stack results in average and peak RSS reductions (up to 11%
and 7% respectively) for some benchmarks, with mostly minimal
performance degredation (3-4% for some benchmarks, ~0% geomean). Each of
these benchmarks was executed with GODEBUG=madvdontneed=1 on Linux; the
performance degredation is even smaller when MADV_FREE may be used, but
the impact on RSS is much harder to measure. Applications that generally
maintain a steady heap size for the most part show no change in
application performance.
These benchmarks are taken from an experimental benchmarking suite
representing a variety of open-source Go packages, the raw results may
be found here:

This change adds a background scavenging goroutine whose pacing is
determined when the heap goal changes. The scavenger is paced to use
at most 1% of the mutator's time for most systems. Furthermore, the
scavenger's pacing is computed based on the estimated number of
scavengable huge pages to take advantage of optimizations provided by
the OS.
The purpose of this scavenger is to deal with a shrinking heap: if the
heap goal is falling over time, the scavenger should kick in and start
returning free pages from the heap to the OS.
Also, now that we have a pacing system, the credit system used by
scavengeLocked has become redundant. Replace it with a mechanism which
only scavenges on the allocation path if it makes sense to do so with
respect to the new pacing system.

In CL 173938, the linker's object file reader was switched over to
selectively create strings backed with read-only mmap'd memory.
In the process a call to r.rd.Offset() was added to readSymName(),
which greatly increased the number of system calls (Offset does a
seek system call).
This patch changes the object file reader so that all reads are done
directly from the mmap'd data if it is present, and adds logic to keep
track of the offset within the rodata consumed so far. Doing this gets
rid of the calls to r.rd.Offset() and the corresponding seek system
calls.
Also as part of this change, hoist the calls to objabi.PathToPrefix
up into the initial setup code for object reading, and store the
result in the reader (since objabi.PathToPrefix was also coming up
as hot in the profile).

In IDE-like applications (and also in tests), there is often a need to
type-check an expression as if it appeared at a particular position in
the source code of an already typed-checked package.
Eval was added to address this need, but did so only partially,
stopping short of exposing a type-annotated expression tree. This
makes it impossible to resolve an expression such as new(T).x and
discover what Object x refers to. CheckExpr exposes that generality.
Eval is now implemented in terms of CheckExpr.
This change includes a test that demonstrates the object resolution

This change is a simple work-around to avoid a compiler crash
and provide a reasonable error message. A future change should
fix the root cause for this problem.
Fixes#23823.

The crypto/tls and crypto/x509 APIs leak PublicKey and PrivateKey types,
so in order to add support for Ed25519 certificates we need the ed25519
package in the stdlib.
It's also a primitive that's reasonable to use directly in applications,
as it is a modern, safe and fast signing algorithm, for which there
aren't higher level APIs. (The nacl/sign API is limiting in that it
repeats the message.)
A few docs changes will come in a follow-up, and a CL will land on
golang.org/x/crypto/ed25519 to make it a type alias wrapper on Go 1.13+.
