[PATCH] D152147: [RISCV] Fold binary op into select if profitable.

[Mikhail Gudim via Phabricator via llvm-commits]

mgudim updated this revision to Diff 529033.
mgudim added a comment.

Addressed comments.
Fixed a bug: the constants were passed to `DAG.FoldConstantArithmetic` in the wrong order.
Moved call to `foldBinOpIntoSelectIfProfitable` after `combineSelectToBinOp` - this way we will not fold binop if the constant of select is already `0` or `-1`.
Minor typo fixes.
