  6. Integrate LLD for MSVC targets via experimental CMake option LDC_WITH… 

    …_LLD

Results in a 7.5% bigger RelWithDebInfo ldc2.exe on Win64 with LLVM 3.9.1.

LLD is currently enforced when building with LDC_WITH_LLD=ON. And LLD
still doesn't support debuginfo (.pdb) generation for MSVC targets.

  1. Add experimental -link-internally switch to enable LLD opt-in 

    And infer CMake LDC_WITH_LLD automatically based on availability of LLVM
3.9+ with LLD headers & libs.
