For PR256:
* cache more values * standardize cache value names * organize configure script per autoconf recommendations (10 sections) * Eliminate some redundancies and complexities in the script * Provide better documentation in the script. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18232 91177308-0d34-0410-b5e6-96231b3b80d8
