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

[Mikhail Gudim via Phabricator via llvm-commits]

mgudim updated this revision to Diff 538821.
mgudim added a comment.

(1) Added a check if `FoldConstantArithmetic` returns null.
(2) Fixed the incorrect use of `ArrayRef`. This was causing a bug, which is not visible when compiled in `Debug` mode.
