Support the WIN64/EFI64 calling convention on all X86_64 platforms
Add a new calling convention FFI_EFI64, alias FFI_WIN64, on all X86_64
platforms. This allows libffi compiled on a 64-bit x86 platform to call
EFI functions.
Compile in ffiw64.c and win64.S on all X86_64 platforms. When compiled
for a platform other than X86_WIN64, ffiw64.c suffixes its functions
with _efi64, to avoid conflict with the platform's actual
implementations of those functions.

src/x86/win64.S: Support compiling on non-WIN64 platforms
Non-WIN64 versions of the GNU assembler don't support the .seh_*
directives for structured exception handling, so wrap them in a macro
that compiles to nothing.
Handle the registers used for the non-Windows x86-64 calling convention
when on a non-Windows platform. Distinguish between cases that should
refer to the native argument registers (defined as arg0, arg1, arg2, and
arg3) and cases that should always refer to the Windows argument
registers.

* Solaris/x86 needs to use EH_FRAME_FLAGS so manually and compiler
generated .eh_frame sections match, otherwise libffi.so fails to link:
* Solaris/x86 /bin/as has different COMDAT syntax; I've disabled it for
the moment.

x86: More Darwin unwind fixups
EHFrame{N} IIRC is a special cue to ld64 that it should treat the unwind
in the object as "special/legacy" .. [these days everything is .cfi_xxxx
(except, cctools-as, as you noted)] .. without that much confusion arises
with ld64's atom-isation of the eh_frame section.
xxxx.eh labels are not needed for darwin ld64 >= 85.2.1 (i.e. darwin9,
xcode 3.1.4) to all intents and purposes, that's all that matters now,
since I think that anyone trying to build on 10.4/darwin8/xcode2.5 would
have to use a later ld64 (from odcctools) for other reasons.

Fix ABI on 32-bit non-Windows x86: go back to trampoline size 10
The trampoline size is part of the ABI, so it cannot change. Move the
logic from the stdcall and thiscall trampolines to the functions they
call, to reduce them both to 10 bytes.
This drops the previously added support for raw THISCALL closures on
non-Windows. (Non-raw THISCALL closures still work.)

Now that non-Windows platforms include win32.S, it needs to support
building as position-independent code. This fixes build failures on
target platforms that do not allow text relocations.

win32.S: Make calls to ffi_closure_SYSV_inner position-independent
Now that non-Windows platforms include win32.S, it needs to support
building as position-independent code. This fixes one source of build
failures on target platforms that do not allow text relocations.

Add support for stdcall, thiscall, and fastcall on non-Windows x86-32
Linux supports the stdcall calling convention, either via functions
explicitly declared with the stdcall attribute, or via code compiled
with -mrtd which effectively makes stdcall the default.
This introduces FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on
non-Windows x86-32 platforms, as non-default calling conventions.
