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.

28eeaed8a9 Revert "coroutine/arm32/Context.S: save/restore the registers via stack" 
This reverts commit 6df1814c08.

It caused a SEGV again:

730aeb2523 Revert 518adcca0a and dbe232e24e 
518adcca0a: "Try using arm32 implementation for fibers."
dbe232e24e: "Order of arguments might be incorrect in arm32 coroutine implementation."

It seems to cause SEGV consistently on Ubuntu armv7l eabihf:

3a5cc345f8 Native coroutine implementation for ppc64le Linux 
* configure.ac: enable fiber coroutine for powerpc64le-linux

* coroutine/ppc64le/Context.S: coroutine_transfer implementation

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.

e64f71f812 Change Makefile rule for assembly to use .S rather than .s 
It is more conventional to use compiler to pre-process and
assemble the `.S` file rather than forcing Makefile to use `.s`.
