r322086 removed the trailing information describing reg classes for each register. This patch adds printing reg classes next to every register when individual operands/instructions/basic blocks are printed. In the case of dumping MIR or printing a full function, by default don't print it. Differential Revision: https://reviews.llvm.org/D42239 llvm-svn: 322867
