For non-constant shifts with an untyped constant shift count, the
spec only said that it must "be converted to unsigned integer type".
go/types accepts any (arbitrarily large) integer value. Both cmd/compile
and gccgo require that the shift count be representable as a uint value
in that case (if the shift count is typed, it may be any unsigned integer
type).
This change adjusts the spec to state what the compilers have been doing
all along. The new wording matches similar rules elsewhere (e.g., for
untyped array and slice indices). Also, while technically this is a
restriction (we could permit arbitrarily large shift counts), in practice
this is irrelevant.
Fixes#14822.

This change removes the punitive language and anonymous reporting mechanism
from the Code of Conduct document. Read on for the rationale.
More than a year has passed since the Go Code of Conduct was introduced.
In that time, there have been a small number (<30) of reports to the Working Group.
Some reports we handled well, with positive outcomes for all involved.
A few reports we handled badly, resulting in hurt feelings and a bad
experience for all involved.
On reflection, the reports that had positive outcomes were ones where the
Working Group took the role of advisor/facilitator, listening to complaints and
providing suggestions and advice to the parties involved.
The reports that had negative outcomes were ones where the subject of the
report felt threatened by the Working Group and Code of Conduct.
After some discussion among the Working Group, we saw that we are most
effective as facilitators, rather than disciplinarians. The various Go spaces
already have moderators; this change to the CoC acknowledges their authority
and places the group in a purely advisory role. If an incident is
reported to the group we may provide information to or make a
suggestion the moderators, but the Working Group need not (and should not) have
any authority to take disciplinary action.
In short, we want it to be clear that the Working Group are here to help
resolve conflict, period.
The second change made here is the removal of the anonymous reporting mechanism.
To date, the quality of anonymous reports has been low, and with no way to
reach out to the reporter for more information there is often very little we
can do in response. Removing this one-way reporting mechanism strengthens the
message that the Working Group are here to facilitate a constructive dialogue.

To avoid confusion caused by the term "named type" (which now just
means a type with a name, but formerly meant a type declared with
a non-alias type declaration), a type declaration now comes in two
forms: alias declarations and type definitions. Both declare a type
name, but type definitions also define new types.
Replace the use of "named type" with "defined type" elsewhere in
the spec.

First steps towards defining type aliases in the spec.
This is a nomenclature clarification, not a language change.
The spec used all three terms 'embedded type', 'anonymous field',
and 'embedded field'. Users where using the terms inconsistently.
The notion of an 'anonymous' field was always misleading since they
always had a de-facto name. With type aliases that name becomes even
more important because we may have different names for the same type.
Use the term 'embedded field' consistently and remove competing
terminology.
For #18130.

We are seeing a bad stack map in #18190. In a copystack, it is
mistaking a slot for a pointer.
Presumably this is caused either by our fledgling dynlink support on
darwin, or a consequence of having two copies of the runtime in the
process. But I have been unable to work out which in the 1.8 window,
so pushing darwin support to 1.9 or later.

This rolls back https://golang.org/cl/27117 partly, softening it so it
only retries POST/PUT/DELETE etc requests where there's no Body (nil
or NoBody). This is a little useless, since most idempotent requests
have a body (except maybe DELETE), but it's late in the Go 1.8 release
cycle and I want to do the proper fix.
The proper fix will look like what we did for http2 and only retrying
the request if Request.GetBody is defined, and then creating a new request
for the next attempt. See https://golang.org/cl/33971 for the http2 fix.
