Hardware single stepping is not currently supported by the linux kernel. In order to support single step debugging, add EmulateInstructionLoongArch to implement the software Single Stepping. This patch only support the simplest single step execution of non-jump instructions. Reviewed By: SixWeining, DavidSpickett Differential Revision: https://reviews.llvm.org/D139158
