CL 36932 (speed up fastrandn) made it faster but introduced
bad interference with some properties of fastrand itself, making
fastrandn not very random in certain ways. In particular, certain
selects are demonstrably unfair.
For Go 1.10 the new faster fastrandn has induced a new fastrand,
which in turn has caused other follow-on bugs that are still being
discovered and fixed.
For Go 1.9.2, just go back to the barely slower % implementation
that we used in Go 1.8 and earlier. This should restore fairness in
select and any other problems caused by the clever fastrandn.
The test in this CL is copied from CL 62530.
Fixes #22253.

If we have
y = <int16> (MOVBQSX x)
z = <int32> (MOVWQSX y)
We used to use this rewrite rule:
(MOVWQSX x:(MOVBQSX _)) -> x
But that resulted in replacing z with a value whose type
is only int16. Then if z is spilled and restored, it gets
zero extended instead of sign extended.
Instead use the rule
(MOVWQSX (MOVBQSX x)) -> (MOVBQSX x)
The result is has the correct type, so it can be spilled
and restored correctly. It might mean that a few more extension
ops might not be eliminated, but that's the price for correctness.

The assembler barfs on large offsets. Make sure that all the
instructions that need to have their offsets in an int32
1) check on any rule that computes offsets for such instructions
2) change their aux fields so the check builder checks it.
The assembler also silently misassembled offsets between 1<<31
and 1<<32. Add a check in the assembler to barf on those as well.

The approach of https://golang.org/cl/43476 turned out incorrect.
The problem is that the sniff introduced by the CL only work for simple
expression. And when it fails it fallback to uint64, not int64, which
breaks backward compatibility.
In this CL, we use DWARF for guessing kind instead. That should be more
reliable than previous approach. And importanly, it fallbacks to int64 even
if it fails to guess kind.

More generally I'm concerned about these tests using
$GOROOT/src/cmd/go as scratch space, especially
combined wtih tg.parallel() - it's easy to believe some other
test might inadvertently also try to write x.exe about the
same time. This CL only solves the "didn't clean up x.exe"
problem and leaves for another day the "probably shouldn't
write to cmd/go at all" problem.

After we detect errors, the AST is in a precarious state and more
likely to trip useless ICE failures. Instead let the user fix any
existing errors and see if the ICE persists. This makes Fatalf more
consistent with how panics are handled by hidePanic.
While here, also fix detection for release versions: release version
strings begin with "go" ("go1.8", "go1.9.1", etc), not "release".

Next
Database drivers should be called from a single goroutine to ease
driver's design. If a driver chooses to handle context
cancels internally it may do so.
The sql package violated this agreement when calling Next or
NextResultSet. It was possible for a concurrent rollback
triggered from a context cancel to call a Tx.Rollback (which
takes a driver connection lock) while a Rows.Next is in progress
(which does not tack the driver connection lock).
The current internal design of the sql package is each call takes
roughly two locks: a closemu lock which prevents an disposing of
internal resources (assigning nil or removing from lists)
and a driver connection lock that prevents calling driver code from
multiple goroutines.

initialized
CL 36428 changed the way nanotime works so on Darwin and Windows it
now depends on runtime.startNano, which is computed at runtime.init
time. Unfortunately, the `runtimeInitTime = nanotime()` initialization
happened *before* runtime.init, so on these platforms runtimeInitTime
is set incorrectly. The one (and only) consequence of this is that the
start time printed in gctrace lines is bogus:
gc 1 18446653480.186s 0%: 0.092+0.47+0.038 ms clock, 0.37+0.15/0.81/1.8+0.15 ms cpu, 4->4->1 MB, 5 MB goal, 8 P
To fix this, this commit moves the runtimeInitTime initialization to
shortly after runtime.init, at which point nanotime is safe to use.
This also requires changing the condition in newproc1 that currently
uses runtimeInitTime != 0 simply to detect whether or not the main M
has started. Since runtimeInitTime could genuinely be 0 now, this
introduces a separate flag to newproc1.
Fixes #21554.

to non-TLS servers
PlainAuth originally refused to send passwords to non-TLS servers
and was documented as such.
In 2013, issue #5184 was filed objecting to the TLS requirement,
despite the fact that it is spelled out clearly in RFC 4954.
The only possibly legitimate use case raised was using PLAIN auth
for connections to localhost, and the suggested fix was to let the
server decide: if it advertises that PLAIN auth is OK, believe it.
That approach was adopted in CL 8279043 and released in Go 1.1.
Unfortunately, this is exactly wrong. The whole point of the TLS
requirement is to make sure not to send the password to the wrong
server or to a man-in-the-middle. Instead of implementing this rule,
CL 8279043 blindly trusts the server, so that if a man-in-the-middle
says "it's OK, you can send me your password," PlainAuth does.
And the documentation was not updated to reflect any of this.
This CL restores the original TLS check, as required by RFC 4954
and as promised in the documentation for PlainAuth.
It then carves out a documented exception for connections made
to localhost (defined as "localhost", "127.0.0.1", or "::1").
Cherry-pick of CL 68170.

[This is a cherry-pick of CL 54090 to the 1.9 release branch.]
gc.Sysfunc must not be called concurrently.
We set up runtime routines used by the backend
prior to doing any backend compilation.
I missed the 387 ones; fix that.
Sysfunc should have been unexported during 1.9.
I will rectify that in a subsequent CL.

Because profile labels are copied from the goroutine into the tag
buffer by the signal handler, there's a carefully-crafted set of race
detector annotations to create the necessary happens-before edges
between setting a goroutine's profile label and retrieving it from the
profile tag buffer.
Given the constraints of the signal handler, we have to approximate
the true synchronization behavior. Currently, that approximation is
too weak.
Ideally, runtime_setProfLabel would perform a store-release on
&getg().labels and copying each label into the profile would perform a
load-acquire on &getg().labels. This would create the necessary
happens-before edges through each individual g.labels object.
Since we can't do this in the signal handler, we instead synchronize
on a "labelSync" global. The problem occurs with the following
sequence:
1. Goroutine 1 calls setProfLabel, which does a store-release on
labelSync.
2. Goroutine 2 calls setProfLabel, which does a store-release on
labelSync.
3. Goroutine 3 reads the profile, which does a load-acquire on
labelSync.
The problem is that the load-acquire only synchronizes with the *most
recent* store-release to labelSync, and the two store-releases don't
synchronize with each other. So, once goroutine 3 touches the label
set by goroutine 1, we report a race.
The solution is to use racereleasemerge. This is like a
read-modify-write, rather than just a store-release. Each RMW of
labelSync in runtime_setProfLabel synchronizes with the previous RMW
of labelSync, and this ultimately carries forward to the load-acquire,
so it synchronizes with *all* setProfLabel operations, not just the
most recent.

The code was adding race.Errors to t.raceErrors before checking
Failed, but Failed was using t.raceErrors+race.Errors. We don't want
to change Failed, since that would affect tests themselves, so modify
the harness to not unnecessarily change t.raceErrors.
