Mark sysv.S as SafeSEH compatible (#438)
It contains no exception handler, so we can just emit the special
@feat.00 symbol to indicate that it's trivially SafeSEH compatible.
SafeSEH only applies to x86 and not x86-64, hence its inclusion in the
x86-specific block. See [1] for details.

Fix x86 SysV closure in PIC mode
The assembly single-line comments swallowed up the remaining assembly
code of the macros due to lack of line-endings.
This is a regression introduced in b7f6d7a.

x86: Solaris fixes
* Solaris/x86 /bin/as doesn't support .org, so I've just disabled the
uses in src/x86/{sysv, unix64}.S, as on Darwin.
* 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.

Apparently, PCC doesn't support the fastcall calling convention.

x86: Remove use of .cfi_escape
The unwind info isn't 100% correct at all points during the epilogue,
and not annotating is just as incorrect as the annotation. This works
better on systems that do not support DW_OP_call_frame_cfa.

x86: Rewrite closures
Move everything into sysv.S, removing win32.S and freebsd.S.

Only push the context for the REGISTER abi; let the rest
receive it in a register.

x86: Rewrite ffi_call
Decouple the assembly from FFI_TYPE_*. Merge prep_args with ffi_call,
passing the frame and the stack to the assembly.
Note that this patch isn't really standalone, as this breaks closures.
