[PATCH] D36734: [PowerPC Peephole] Constants into a join add, use ADDI over LI/ADD.

[Tony Jiang via Phabricator via llvm-commits]

jtony created this revision.

Two blocks prior to the join each perform an li and the the join block has an add using the initialized register. Optimize each predecessor block to instead use addi and delete the li's and add.
