Add a monstrous hack to improve X86ISelDAGToDAG compile time.
- Force NDEBUG on in any Release build. This drops the compile time to ~100s from ~600s, in Release mode. - This may just be a temporary workaround, I don't know the true nature of the gcc-4.2 compile time performance problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86695 91177308-0d34-0410-b5e6-96231b3b80d8
