[utils] Remove ancient scripts using llvm-config --src-root

[MaskRay]

Summary

The last effective changes for the 4 scripts were more than 10 years ago.
They do grep and lines of code counting which have mature modern replacements
(rg, tokei, etc).

[mgorny]

Well, I'm not opposed to seeing them go but let's try to see if we can contact their authors first.

Alternatively to removing them, I suppose we could replace the llvm-config call with computing the path relatively to $0.

[lattner]

I have no objection to removing these!

-# This script is a general purpose "apply" function for the source files in LLVM
-# It uses "find" to locate all the source files and then applies the user's 
-# command to them. As such, this command is often not used by itself much but
-# the other find related tools (countloc.sh,llvmgrep,getsrcs.sh,userloc.sh) are
-# all based on this script.  This script defines "what is a source file" in 
-# LLVM and so should be maintained if new directories, new file extensions, 
-# etc. are used in LLVM as it progresses.
-#
-# Usage:
-#  llvmdo [-topdir DIR] [-dirs "DIRNAMES..."] [-code-only] PROGRAM ARGS...
-#
-# The -topdir option allows you to specify the llvm source root directly. If it
-# is not specified then it will be obtained with llvm-config which must be built
-# and in your path.
-#
-# The -dirs argument allows you to specify the set of directories that are 
-# searched. The default list of directories searched is:
-#   include lib tools utils runtime autoconf docs test examples projects
-# Note that you must use quotes around the list of directory names. 
-#
-# The -code-only option specifies that only those files that are considered 
-# "code" should be visited. HTML documentation is considered code, but things 
-# like README files, etc. are not.
-#
-# Finally, you simply specify whatever program you want to run against each 
-# file and the arguments to give it. The PROGRAM will be given the file name 
-# as its last argument.
