Have you tried to link in the shell directly, without VisualD? If 
you get that LNK error, that's from the MS linker, which of 
course doesn't have the faintest idea about LLVM bitcode. So 
lld-link.exe is required (and as said, the default linker in such 
a scenario unless another build tool interferes).

Note that the ldc2 binaries in the official LDC packages are 
built with LTO (across C++ and D, incl. druntime from D host 
compiler), so it's not like LTO would be completely untested and 
totally unbuggy, as the reports here in the forum might suggest 
(as always, the majority for which it's working is silent).
