Even though this argument design conflates two separate concepts (ABI and hardware/software implementation), I chose to go with it since users are liekly know it from GCC and the combination of softloat operations with hardfloat ABI makes no sense. I didn't implement it for old LLVM versions, as ARM EABI exception handling requires LLVM 3.3+ anyway, without which LDC would be useless anyway.
