[PATCH] D100769: [RISCV] Refactor an optimization of addition with immediate

[Ben Shi via Phabricator via llvm-commits]

benshi001 added a comment.

I have removed the ADDIW parts, this patch is simply a refactoring of the oringal optimization, changeing from DAG to TD. There is no extra test needed, since llvm/test/codegen/riscv/add-imm.ll has covered all cases.
