s390: Inline and tidy ffi_prep_args
As per discussion with Ulrich Weigand, document the restrictions
on the code within ffi_call_int as we simultaneously prepare
stack frames for ffi_call_SYSV and the target function.

s390: Use pc-relative insns in 31-bit mode
It's silly to stick to esa/390 features when the compiler won't.
Detect when brasl and larl are used by the compiler and then use
them in the assembly.

x86: Handle void arguments as if an empty structure
Since libffi currently doesn't allow empty structures, libgo
currently maps them to ffi_type_void. Given that we'll abort
on this case, handle it gracefully.

powerpc: Fix ffi_go_closure_linux64

register dependency chain.
(ffi_go_closure_linux64): Don't load r11 or r2.

This is a port of
http://gcc.gnu.org/viewcvs?rev=207763&root=gcc&view=rev
aka GCC PR libffi/60073, to the rewritten Sparc codebase.
Supposedly, we should have seen failures with the existing

sparc: Re-add abi compliant structure support
The original code, removed in the "rewrite" patch, was incorrect for
large structures, and required dynamic allocation of a trampoline on
every ffi_call.
Instead, allocate a 4k entry table of all possible structure returns.
The table is 80k, but is read-only and dynamically paged, which ought
to be better than allocating the trampoline.
This is difficult to test with gcc. One can only use -O0 at present.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63668.

sparc: Rewrite everything
It's impossible to call between v8 and v9 ABIs, because of the stack bias
in the v9 ABI. So let's not pretend it's just not implemented yet. Split
the v9 code out to a separate file.
The register windows prevent ffi_call from setting up the entire stack
frame the assembly, but we needn't make an indirect call back to prep_args.

x86: Force FFI_TYPE_LONGDOUBLE different from FFI_TYPE_DOUBLE
There are few abis that set double = long double. Eliminate the
conditional compilation and let this code simply be unused there.

x86: Remove some conditional compilation
Removal of ifdefs made possible to due to ffi_abi unification.

x86: Tidy ffi_abi
The x86_64 unix port only handles one ABI; don't define all of the
other symbols. The UNIX64 symbol retains the same value.
The i386 ports ought to have the same symbols, even if we can't yet
unify the values without incrementing the libffi soname.

testsuite: Fix return_complex2 vs excessive precision
Use the previously computed rc2 to validate, rather than
recomputing a floating point result with excess precision.

We can better support structure returns, and as prep for
complex types.

win64: Rewrite
It's way too different from the 32-bit ABIs with which it is
currently associated. As seen from all of the existing XFAILs.

x86-64: Support go closures
Dumps all of the hand-coded unwind info for gas generated. Move jump
table data into .rodata. Adjust ffi_call_unix64 to load the static
chain. Split out sse portions of ffi_closure_unix64 to
ffi_closure_unix64_sse rather than test cif->flags at runtime.

Add entry points for interacting with Go
A "ffi_go_closure" is intended to be compatible with the
function descriptors used by Go, and ffi_call_go sets up
the static chain parameter for calling a Go function.
The entry points are disabled when a backend has not been
updated, much like we do for "normal" closures.
