Change from using __go_set_closure to passing the closure
value in the static chain field.  Uses new backend support for
setting the closure chain in a call from C via
__builtin_call_with_static_chain.  Uses new support in libffi
for Go closures.

The old architecture specific support for reflect.MakeFunc is
removed, replaced by the libffi support.

All work done by Richard Henderson.

	* go-gcc.cc (Gcc_backend::call_expression): Add chain_expr argument.
	(Gcc_backend::static_chain_variable): New method.

This upgrades all of libgo other than the runtime package to
the Go 1.4 release.  In Go 1.4 much of the runtime was
rewritten into Go.  Merging that code will take more time and
will not change the API, so I'm putting it off for now.

There are a few runtime changes anyhow, to accomodate other
packages that rely on minor modifications to the runtime
support.

The compiler changes slightly to add a one-bit flag to each
type descriptor kind that is stored directly in an interface,
which for gccgo is currently only pointer types.  Another
one-bit flag (gcprog) is reserved because it is used by the gc
compiler, but gccgo does not currently use it.

There is another error check in the compiler since I ran
across it during testing.

If named types with similar names are defined inside of methods
with similar names, it was possible that the mangled type names would be
the same, leading to multiple definitions of type descriptor and
garbage collection info variables.
This can only occur with similarly named methods across different
receivers, so we use the receiver name to distinguish.

They are never necessary, and they can cause problems when a
thunk is used to pass an unexported type from a different
package to a function defined in that package.  The resulting
struct type may need to call the comparison routine from the
other package, which will fail because the type is not
exported.  This will be bug492 in the master testsuite.
