Even for a stdcall function, the stack alignment is still the
responsibility of the caller. Remember the original, not stack-aligned
argument size, but align when setting up a stack frame. In
ffi_closure_inner, return the true argument size, so that
ffi_[go_]closure_STDCALL doesn't adjust too much.
Use docker images and qemu to test libffi for non-x86 architectures on
travis-ci.
Use the LIBFFI_TEST_OPTIMIZATION environment variable to
force specific optimization levels at test time.
* powerpc: Silence warnings about unused labels
* powerpc: Fix a couple of comments
* powerpc: Fix alignment after float structs
* powerpc: Don't pad rvalues copied from FP regs
* powerpc: Add missing check in struct alignment
* powerpc: Support homogeneous long double structs
* libffi: added ARM64 support for Windows
1. ported sysv.S to win64_armasm.S for armasm64 assembler
2. added msvc_build folder for visual studio solution
3. updated README.md for the same
4. MSVC solution created with the changes, and below test suites are tested
with test script written in python.
libffi.bhaible
libffi.call
5. Basic functionality of above test suites are getting passed

* Update README.md
Before the change hand-crafted .eh_frame section contained
ABS relocation and caused TEXTREL tag to be emitted:
```
$ ./configure --host=hppa2.0-unknown-linux-gnu LDFLAGS=-Wl,-z,text
$ make
...
/usr/libexec/gcc/hppa2.0-unknown-linux-gnu/ld:
read-only segment has dynamic relocations.
```
Link failure is caused by absolute address of FDEs
encoded into .eh_frame entries.
Fixed TEXTREL by using pcrel (instead of ABS) encoding
for absolute addresses (__PIC__ code) by adding augmentation
information ("zR" CIE type).
All tests still pass on hppa2.0. The specific tests that still pass
and exercise this code path:
testsuite/libffi.call/unwindtest.cc
testsuite/libffi.call/unwindtest_ffi_call.cc

* x86: Correct testing for 64-bit x86-64

need to check both __ILP32__ and __i386__ for 64-bit x86-64.
* x86: Check __i386__ instead of i?86-*-* targets
Since passing -m32 to x86-64 compiler will generate i386 code, we need
to check __i386__ instead of i?86-*-* targets for i386 targets.
* i386: Properly passing integer parameters in registers
For thiscall and fastcall, if the paramter passed as 64-bit integer or
struct, all following integer paramters will be passed on stack.
* test: Add ABI_ATTR to callback_code
Add ABI_ATTR to callback_code to properly test different ABIs.
