Aside from moving the actual files, this patch only updates the build system and the source file comments under lib/... that are relevant. I'll be updating other docs and other files in smaller subsequnet commits. While I've tried to test this, but it is entirely possible that there will still be some build system fallout. Also, note that I've not changed the library name itself: libLLVMCore.a is still the library name. I'd be interested in others' opinions about whether we should rename this as well (I think we should, just not sure what it might break) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171359 91177308-0d34-0410-b5e6-96231b3b80d8
