LGTM with one nit comment.



================
Comment at: llvm/lib/Target/PowerPC/PPCISelDAGToDAG.cpp:4461
+
+    // It is not 16-bit imm that means we need two instructions at least if
+    // using "and" instruction. Try to exploit it with rotate mask instructions.
----------------
imm16 should be handle as well in new patch?  comment should update?
