The test for #9400 relies on an assembler function that manipulates
the stack pointer. Meanwile, it uses a global variable for
synchronization. However, position independent code on 386 use a
function call to fetch the base address for global variables.
That function call in turn overwrites the Go stack.

Fix that by fetching the global variable address once before the
stack register manipulation.

When a wrapper method calls the real implementation, it's not possible to use a
tail call when dynamic linking on ppc64le. The bad scenario is when a local
call is made to the wrapper: the wrapper will call the implementation, which
might be in a different module and so set the TOC to the appropriate value for
that module. But if it returns directly to the wrapper's caller, nothing will
reset it to the correct value for that function.

This change causes TLS handshake messages to be buffered and written in
a single Write to the underlying net.Conn.

There are two reasons to want to do this:

Firstly, it's slightly preferable to do this in order to save sending
several, small packets over the network where a single one will do.

Secondly, since 37c28759 errors from
Write have been returned from a handshake. This means that, if a peer
closes the connection during a handshake, a “broken pipe” error may
result from tls.Conn.Handshake(). This can mask any, more detailed,
fatal alerts that the peer may have sent because a read will never
happen.

Buffering handshake messages means that the peer will not receive, and
possibly reject, any of a flow while it's still being written.

Since CL 23620, TestAssembly is failing on Plan 9.

In CL 23620, the process environment is passed to 'go tool compile'
after setting GOARCH. On Plan 9, if GOARCH is already set in the
process environment, it would take precedence. On Unix, it works
as expected because the first GOARCH found takes precedence.

This change uses the mergeEnvLists function from cmd/go/main.go
to merge the two environment lists such that variables with the
same name in "in" replace those in "out".

This fixes `go test go/types`.

https://golang.org/cl/23487/ introduced this code which contains
two unused variables (declared and assigned to, but never read).
cmd/compile doesn't report the error due open issue #8560 (the
variables are assigned to in a closure), but go/types does. The
build bot only runs go/types tests in -short mode (which doesn't
typecheck the std lib), hence this doesn't show up on the dashboard
either.

We cannot call b.Fatal and friends in the goroutine. Communicating
the error to the invoking function requires a channel or a mutex.
Unless the channel/sycnhronized variable is tested in each iteration
that follows, the iteration blocks if there's a failure. Testing in
each iteration may affect benchmark times.

One could use a time-out but that time depends on the underlying system.
Panicking seems good enough in this unlikely case; better than hanging
or affecting benchmark times.

Both compilers and also go/types don't permit duplicate types in
type switches; i.e., this spec change is documenting a status quo
that has existed for some time.

Furthermore, duplicate nils are not accepted by gccgo or go/types;
and more recently started causing a compiler error in gc. Permitting
them is inconsistent with the existing status quo.

Rather than making it an implementation restriction (as we have for
expression switches), this is a hard requirement since it was enforced
from the beginning (except for duplicate nils); it is also a well
specified requirement that does not pose a significant burden for
an implementation.
