When using lldb and/or gdb I frequently get odd std::string failures when using the IR printing instructions we have now. This adds the methods Instruction::Dump(), BasicBlock::Dump() and Function::Dump() to emit the output of the pretty print to stderr. With this I can now reliably print IR from gdb and lldb sessions.
