Should we finally ditch the 32-bit build of dmd?

Yes, there might be 32-bit x86 systems and just because of this I 
say we should ditch dmd. I knew this were coming, that the dmd 
backend would be gradually abandoned because of lack of 
resources. Also, GDC/LDC offers a range of x86 micro 
architectures to optimize for which is out of scope for dmd. This 
is particularly interesting for embedded systems that often use 
odd x86 CPUs. This will eventually happen to x86-64 as well and 
I'm starting the timer.

Instead D should take advantage of CPU support that comes with 
GDC/LDC and the infrastructure around them.
