Move the architecture-specific settings out of configure.ac into a new
shell script goarch.sh. Use the new script to collect the values for
all architectures to make them available in go/types.
Also fix cmd/vet to pass the right compiler when it calls SizesFor.
This fixes cmd/vet for systems that are not implemented in the gc
toolchain, such as alpha and ia64.

GCC always recognizes the -fsplit-stack option, but then tests whether
it is supported by the selected target. If not, it reports
cc1: error: ‘-fsplit-stack’ is not supported by this compiler configuration

When compiling runtime, it is not allowed for local variables
and closures to be heap allocated. In one test, there is a go
statement with a closure. In the gc compiler, it distinguishes
capturing variable by value vs. by address, and rewrites it to
passing the captured values as arguments. Currently we don't
have this, and the escape analysis decides to heap allocate the
closure and also the captured variables, which is not allowed.
Work around it by passing the variables explicitly.
This is in preparation of turning on escape analysis for the
runtime.

This is in preparation of turning on escape analysis for the
runtime.
- In gccgo, systemstack is implemented with mcall, which is not
go:noescape. Wrap the closure in noescape so the escape analysis
does not think it escapes.
- Mark some C functions go:noescape. They do not leak arguments.
- Use noescape function to make a few local variables' addresses
not escape. The escape analysis cannot figure out because they
are assigned to pointer indirections.

The functions cgoCheckPointer and cgoCheckResult are called by code
generated by cgo. That means that we need to export them using
go:linkname, as otherwise they are local symbols. The cgo code
currently uses weak references to only call the symbols if they are
defined, which is why it has been working--the cgo code has not been
doing any checks.

In the 1.9 upgrade I took out the word "goroutine" from a traceback
showing a goroutine running in C code, to let TestCgoNumGoroutine
pass. However, it turns out that some code is actually checking for
that string; for example,
https://github.com/grpc/grpc-go/blob/master/test/leakcheck/leakcheck.go#L44
So keep the message the same, and change the test.

In preparation for upgrading libgo to the 1.9 release, this
approximately incorporates https://golang.org/cl/37661 and
https://golang.org/cl/38351.
CL 37661 changed the gc compiler such that the select statement simply
returns an integer which is then used as the argument for a switch.
Since gccgo already worked that way, this just adjusts the switch code
to look like the gc switch code by removing the explicit case index
expression and calculating it from the order of calls to selectsend,
selectrecv, and selectdefault.
CL 38351 simplifies the channel code by not passing the unused channel
type descriptor pointer.

This adds much of https://golang.org/cl/35731 and
https://golang.org/cl/35732 to the gofrontend code.
This is a step toward updating libgo to the 1.9 release. The
gofrontend already supports type aliases, and this is required for
correct support of type aliases when used as embedded fields.
The change to expressions.cc is to handle the << 1, used for the
newly renamed offsetAnon field, in the constant context used for type
descriptor initialization.
