Fix building for arm windows with mingw toolchains (#631)
* arm: Check _WIN32 instead of _M_ARM or _MSC_VER for detecting windows
This matches what was done for ARM64 in
c06468fa6674d3783a0edb1d0fae9afc8bc28513.
* arm: Only use armasm source when building with MSVC
When building for windows/arm with clang, the normal gas style .S
source works fine (if fixed up to support thumb and other windows
specifics).
This matches what was done for ARM64 in
c06468fa6674d3783a0edb1d0fae9afc8bc28513.
* arm: Fix sysv.S to work in thumb mode
Align cases in jump tables (adding nop padding to make sure each
case starts where expected).
Rewrite instructions that add directly to the pc register.
For ffi_closure_ret, factor out a call_epilogue subroutine that
restores both sp and pc from the stack; the thumb version of ldm
can't load into the sp register. To avoid excessive ifdeffing, keep
using call_epilogue in arm mode, but keep the shorter "ldm sp, {sp, pc}"
epilogue in that case.
* arm: Add win32 version of trampoline to sysv.S
This matches the version of it in sysv_msvc_arm32.S. The calling
C code expects a specific form of the trampoline on windows; make
sure these work the same on windows regardless of the form of
assembly used.
* arm: Avoid optimizing out clearing the thumb bit of ffi_arm_trampoline
We clear the thumb bit of ffi_arm_trampoline with a bitmask before
memcpying its instructions into closure->tramp.
If the bit isn't cleared, the memcpy of the trampoline function
copies the wrong instructions.
If the ffi_arm_trampoline symbol is declared as an array of int,
the compiler can assume that it is aligned to a 4 byte boundary
and the bitmask operation is a no-op, and optimize it out.
See https://godbolt.org/z/dE3jE1WTz; both Clang and GCC optimize
out the bitmask as it is, while MSVC doesn't. By declaring the
trampoline as an array of unsigned char, the bitmask works as
intended.

libffi/x86: Always check __x86_64__ for x32 hosts (#601) (#602)
Since for x86_64-*x32 and x86_64-x32-* hosts, -m32 generates ia32 codes.
We should always check __x86_64__ for x32 hosts.

> The current FreeBSD/ARM __clear_cache() implementation does nothing #if

> cognet@ advises this is an issue for anything !Apple that is using the

Fix building for aarch64 windows with mingw toolchains (#555)
* aarch64: Check _WIN32 instead of _M_ARM64 for detecting windows
This fixes building for aarch64 with mingw toolchains. _M_ARM64 is
predefined by MSVC, while mingw compilers predefine __aarch64__.
In aarch64 specific code, change checks for _M_ARM64 into checks for
_WIN32.
In arch independent code, check for
(defined(_M_ARM64) || defined(__aarch64__)) && defined(_WIN32)
instead of just _M_ARM64.
In src/closures.c, coalesce checks like
defined(X86_WIN32) || defined(X86_WIN64) || defined(_M_ARM64)
into plain defined(_WIN32). Technically, this enables code for
ARM32 windows where it wasn't, but as far as I can see it, those
codepaths should be fine for that architecture variant as well.
* aarch64: Only use armasm source when building with MSVC
When building for windows/arm64 with clang, the normal gas style .S
source works fine. sysv.S and win64_armasm.S seem to be functionally
equivalent, with only differences being due to assembler syntax.

Since x32 doesn't support WIN64/EFI64, don't include it for x32. Also
x32 has sizeof size_t == 4. But TARGET should be X86_64.

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.

configure: Move target source selection into configure.host
This eliminates the AM_CONDITIONAL ugliness, which eliminates

At the same time, properly categorize the EXTRA_DIST files
