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.

the llvm source root from the llvm-config command. The dependency now is
that the correct llvm-config command is in the path. For most developers
this is the case.

determine the top directory. This allows the tool to find the correct top
directory when you have something like:

   /x/llvm
   /x/llvm2
   /x/llvm3

Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.

replacement for getsrcs.sh which now generates too much text to put on a
Linux command line. The approach taken with llvmgrep is to execute a find
command and execute a grep on each file that matches the name pattern. The
arguments to this script are the same as those of egrep. Note that the -H
and -n options to egrep will always be passed so that you always get the
file and line number of matches.
