In https://golang.org/cl/111097 the gc version of cmd/go was updated
to include some gofrontend-specific changes. The gofrontend code
already has different versions of those changes; this CL makes the
gofrontend match the upstream code.

These tests used to be disabled in the gofrontend since the go tool
didn't support build IDs for the gofrontend. It does now, so enable
the tests again.

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.

Add missing .a files. These should have been committed with the

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
Check for that error message when deciding whether a compiler option works.

Using -funwind-tables is necessary to permit Go code to correctly
throw a panic through C code. This hasn't been necessary in the past
as -funwind-tables is the default on x86. However, it is not the
default for PPC AIX.

This removes the old names for the 3 main MIPS ABIs: mipso32, mipsn32
and mipsn64. It also removes the mipso64 ABI which has no equivalent
architecture name in go. This ABI has been dead for sometime and I doubt
anyone will miss it.

The go tool will pass -I objdir as one of the flags, where objdir is
the temporary build directory. Remove that from _cgo_flags: we don't
need it, and it will be different each time.
Sort the flags to avoid the unpredictable map iteration order.
This matters for gccgo because for a package that uses cgo, the go
tool when building for gccgo will store the _cgo_flags file in the
archive. That means that we want to generate identical _cgo_flags for
every run.
The test for this is the cmd/go testsuite, to follow in a future CL.

Along with the update this fixes a problem that was always present but
only showed up with the new reflect test. When a program used a
**unsafe.Pointer and stored the value in an interface type, the
generated type descriptor pointed to the GC data for *unsafe.Pointer.
It did that by name, but we were not generating a variable with the
right name.

The go/build package does not know that gccgo's standard packages don't
