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.)
64-bit Windows already used this check; make it universal, and use it in
place of an ifdef on X86_WIN32, to handle non-Windows platforms that use
the underscore, such as Darwin.
When sizeof(size_t) != sizeof(unsigned), adding a size_t to cif->bytes
produces a "possible loss of data" warning. However, the size_t in
question refers to the size of a single parameter. Use a cast to avoid
the warning.
Newer versions of Darwin generate the necessary stub functions
automatically and just need a call instruction, but accomodating older
versions as well requires adding the stub.
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.

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.
