Make all tools that use llvmdo have a -topdir option that allows the top

source dir for LLVM to be specified explicitly. This removes the dependency
on the llvm-config script. If the option is not given, then the scripts use
llvm-config which should be both built and in the PATH. This arrangement
provides a useful default for most developers but also allows the nightly
tester to execute countloc.sh before llvm-config is built and without
altering the PATH.

 # This script just prints out the path names for all the source files in LLVM.
+# The optional -topdir option can be used to specify the top LLVM source 
+# directory. Without it, the llvm-config command is consulted to find the
+# top source directory.
 #
 # Note that the implementation is based on llvmdo. See that script for more
 # details.
