I still think having a whole second "bound" version is kind of disgusting, but 
I'm a bit biased because I don't use the "bound" stuff at all (and consider 
_that_ the kind of complexity that tcc probably shouldn't do), but oh well.

I moved all the i386 specific files into an "i386" subdirectory.  I'll 
probably make an arm one at some point, but not right now.  This was just so 
the clutter of two more x86 specific files didn't get added to the top 
directory. :)

I'm not exactly happy with the patch, but it's certainly better than not 
having it, and I can't think how to improve it, so:

Applied.
