* Renamed getOpcode to getOpcodeName * Changed getOpcodeName to return a const char * instead of string * Added a getOpcode method to replace getInstType * Changed code to use getOpcode instead of getInstType git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152 91177308-0d34-0410-b5e6-96231b3b80d8
