4 IR files (new/old, with/without inlining).
I'm hitting:
Assertion failed: (!Node || !ResNo || ResNo < Node->getNumValues()) && "Invalid
result number for the given node!", file
C:\LDC\llvm\include\llvm/CodeGen/SelectionDAGNodes.h, line 1038
when compiling a tiny D file with LDC using LLVM 5.0 (tested for Linux and
Windows-MSVC targets). It requires debuginfos output AND enabled inlining (no
other optimizations required). That code used to work; recent LDC has only
minimally changed the IR (in-place construction in one function), and that
seems to trigger it.
The tiny relevant IR diff is here:

Also happens with LLVM 4.0.1 for Linux targets.</pre>
