[PATCH] D29605: [lanai] Avoid unnecessary AND'ing for brcond.

[Jacques Pienaar via Phabricator via llvm-commits]

jpienaar created this revision.

i32 output from SETCC is 0 or 1, but the backend was inserting an explicit and with 0x1 when output of SETCC's were combined and consumed by brcond. Instead, if all the operands are bitwise binary operations/selects of SETCC outputs then avoid the additional and.
