Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo class to support the Clang MicroBlaze target. Additionally, minor fixes which remove some unused PIC code (PIC is not supported yet in the MicroBlaze backend) and removed some unused variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97054 91177308-0d34-0410-b5e6-96231b3b80d8
