Not a lot but a few, including DynamicLibrary.Shutdown:

  Failed Tests (4):
    LLVM-Unit :: 
Support/DynamicLibrary/./DynamicLibraryTests.exe/DynamicLibrary.Shutdown
    LLVM :: ExecutionEngine/MCJIT/multi-module-sm-pic-a.ll
    LLVM :: ExecutionEngine/OrcMCJIT/multi-module-sm-pic-a.ll
    LLVM :: ExecutionEngine/OrcMCJIT/stubs-sm-pic.ll

And the MCJIT ones seem intermittent (different ones fail each time).

I guess that's just a problem with a larger number of cores then.

I'm going to concentrate on the standalone port as I think that's the way 
forward. If I get that working then can work through the other issues.
