Use local Makefile.rules

This patch changes the build system to use its own copy of Makefile.rules (taken from a recent svn snapshot). Also added a --with-llvm-build-mode flag and changed the default runtime library configuration to Release+Asserts. Makefile.rules was modified to support --with-llvm-build-mode and older versions of LLVM (tested 2.7 and 2.8). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@131584 91177308-0d34-0410-b5e6-96231b3b80d8
