Subject: [PATCH] A utility to run an arbitrary program on each of the LLVM
 source files. This is like llvmgrep but instead of running grep, it runs the
 command given by the first argument. For example, to find the top ten files
 with the most lines in llvm, you could:

utils/llvmdo wc -l | sort -nb | tail

Or, to find any source files with the wrong permissions, you could:

utils/llvmdo ls -l | grep -v rw-r--r--

Hopefully, you get the idea.
