Have the AutoRegen.sh script prompt the user for the LLVM src and obj
directories if it can't find them. Then, replace those values into the configure.ac script and pass them to the LLVM_CONFIG_PROJECT so that the values become the default for llvm_src and llvm_obj variables. In this way the user is required to input this exactly once, and the scripts take it from there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27798 91177308-0d34-0410-b5e6-96231b3b80d8
