When will you implement cent and ucent?

With LDC's support for inline LLVM IR 
(https://wiki.dlang.org/LDC_inline_IR), I think we can quite 
easily have a much better `core.int128` solution for LDC at 
least. Coupled with LLVM's compiler-rt builtins library, which 
should provide performant library fallbacks for targets with 
limited hardware support. So that a druntime `Cent` solution 
should be on-par with clang's `__int128`.

The existing generic software implementation is still useful for 
CTFE.
