clang-p2996/llvm/test/CodeGen/CSKY/ldst-i.ll
Zi Xuan Wu a556ec8861 [CSKY] Complete codegen of basic arithmetic and load/store operations 
Complete basic arithmetic operations such as add/sub/mul/div, and it also includes converions
and some specific operations such as bswap.Add load/store patterns to generate different addressing mode instructions.

Also enable some infra such as copy physical register and eliminate frame index.
