this is maybe the most horrible gcc builtin ever invented!  Is it
really a good idea to duplicate it in LLVM?  I know it's more work,
but I'd much rather BUILTIN_OBJECT_SIZE was mapped to a bunch of
code and perhaps several LLVM intrinsics, but where the intrinsics
each have a clear, clean, sensible and logical definition...

Ciao,

Duncan.
