LLVM IR influence on compiler debugging

I remember some small limits in the LLVM back-end, like not being 
able to use zero bits to implement fixed-size zero length arrays. 
And something regarding gotos in inline asm. I don't know if 
those little limits are now removed.

The D reference compiler can't be DMD forever.

Is LDC2 going to work on Windows32 bit too?
