Roman Lebedev 4792a641c6 Reland [InstCombine] Fold ((X - Y) - Z) to X - (Y + Z) (PR49858) ... This reverts commit a547b4e26b311e417cd51100e379693f51a3f448, relanding commit 31d219d2997fed1b7dc97e0adf170d5aaf65883e, which was reverted because there was a conflicting inverse transform, which was causing an endless combine loop, which has now been adjusted. Original commit message: https://alive2.llvm.org/ce/z/67w-wQ We prefer `add`s over `sub`, and this particular xform allows further folds to happen: Fixes https://bugs.llvm.org/show_bug.cgi?id=49858		2021-04-07 12:06:25 +03:00
