Subject: Added a tool to more accurately count the lines of code. The previous
 utility, getsrcs.sh suffered from two problems: (1) it generated command
 lines too long for some platforms and (2) it searched the projects diretory
 which now contains the llvm-test module (in nightly tester) but we don't want
 to include the test code in our LOC calculation. This script should be
 maintained as LLVM adds new top level directories that contain source code.
