Fix paths; AutoRegen.sh changes its current working directory to be the
autoconf directory, but these paths need to be relative to the main
source directory. Patch originally by Dan Gohman, r67655.
Also, cause configure.ac to find absolute paths to LLVM source and
object trees. Together, fixes PR1220.
