transformed to the final instruction variant. An example would be dsrll which is transformed into dsll32 if the shift value is greater than 32. For direct object output we need to do this transformation in the codegen. If the instruction was inside branch delay slot, it was being missed. This patch corrects this oversight. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162779 91177308-0d34-0410-b5e6-96231b3b80d8
