Add a small utility class to configure IR printers. This will allow
printers to do neat and wonderful things when printing debug information. The ideas is to allow passes to configer printers to emit pass-specific information when dumping IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76602 91177308-0d34-0410-b5e6-96231b3b80d8
