Fix LLVM target initialization to deal with sociopathic outside projects
that like to randomly define things like "X86", regenerate autoconf bits and update cmake. Fixes PR7852. Patch by Xerxes Rånby! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112499 91177308-0d34-0410-b5e6-96231b3b80d8
