Nemanja Ivanovic 6cc31ca814 [PowerPC] Do not emit record-form rotates when record-form andi suffices 
Up until Power9, the performance profile for rlwinm., rldicl. and andi. looked
more or less equivalent. However with Power9, the rotates are still 2-way
cracked whereas the and-immediate is not.

This patch just ensures that we don't emit record-form rotates when an andi.
is adequate.

As first pointed out by Carrot in https://bugs.llvm.org/show_bug.cgi?id=30833
(this patch is a fix for that PR).
