The gccgo-specific iword function was checking v.kind, but for
a method value that is always Func.  Fix to check v.typ.Kind()
instead.

This changes the compiler and runtime to not pass a closure
value as the last argument, but to instead pass it via
__go_set_closure and retrieve it via __go_get_closure.  This
eliminates the need for function descriptor wrapper functions.
It will make it possible to retrieve the closure value in a
reflect.MakeFunc function.

This should be more efficient everywhere, and appears to be
required on Solaris.

A function that returns an interface type and returns a value
that requires memory allocation will try to allocate while
appearing to be in a syscall.  This patch lets that work.

This fixes a problem on Solaris, where end is not defined in
the main program but comes from some shared library.  This
only matters for 32-bit targets.

This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct.  The first field of
the struct points to the function code.  The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions.  For each call to a function, the address of the
function descriptor is passed as the last argument.

This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.

runtime: Support Solaris AMD64 in lfstack.
The address space layout is similar on SPARC64 and AMD64 when

The mmap() call which reserves the arena should have MAP_NORESERVE
flag as in typical cases this memory will never be (fully) needed.
This matters in environments which do not do Linux style memory
overcommit, such as OpenIndiana/OpenSolaris/Solaris.

The MAP_NORESERVE flag does not exist on all operating systems
(for example FreeBSD). Therefore we define it to zero value in
case it does not exist.

Fixes issue 21.
