	Extract correct processor name for ARM64 Macs

	Prefix export symbol prefix to coroutine_transfer

	Revert "Revert "[ruby/fiddle] Use ffi_closure_free by default.
	 (#20)""

	This reverts commit efd641ffab.

	This changeset seems to be needed to suppress a warning on Ubuntu 20.04
	20200304T033004Z.log.html.gz
	```

	  264 |     result = ffi_prep_closure(pcl, cif, callback, (void *)self);
	      |     ^~~~~~
	```

	I guess there was a reason why the commit was reverted (maybe some CIs
	failed?), so try it again.

853d91a04a Fix coroutine support on win32 
Ruby master branch currently fails on win32 MINGW at this spec:
https://github.com/ruby/spec/blob/master/core/thread/element_set_spec.rb

MINGW makes use of setjmp3() implemented in MSVCRT.DLL.
This function traverses the SEH list up to a terminating pointer 0xFFFFFFFF.
It therefore currently segfaults on NULL.
The SEH linked list must be terminated by 0xFFFFFFFF instead of NULL.

This fixes the issue mentioned here:

Make fiber_pool more conservative on platforms with limited address space. 
We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address
space is 32-bits or less. Fiber pool implementation enables more book
keeping, and reduces upper limits, in order to minimise address space
utilisation.

Add coroutine context switch for i386-mingw32 
It's essentially a translation of Context.asm from Intel
to AT&T syntax.

c5fe904f6e Fix for coroutine/win32/Context.obj 
* coroutine/win32/Context.asm: old ml version 9 needs CPU
  directive before `.model` directive.

* win32/Makefile.sub: specify object directories to separate Win32
  and Win64 targets.  Win32 rule was overridden by Win64 rule and
  just ignored.
