[PATCH] D104180: [NFC] [LICM] Create LoopNest Invariant Code Motion (LNICM) pass

[toshiki maekawa via Phabricator via llvm-commits]

uint256_t added a comment.

Actually, LNICM is to enable other optimizations in loop pipeline that require perfect loop nest by hoisting innermost invariants out of loop nest at once.
I said that LNICM can efficiently perform LICM, but after tweaking the code and running some tests, I realized that it might not get faster.
However, even if it gets no faster, LNICM is worth adding as a new pass.
