Commit 203cd01b54ddd720be17b8e19207ff5af4a22d4c by saghir [PowerPC] [NFC] Add Big-Endian checks for existing MMA tests This patch adds Big-Endian checks for the existing MMA test cases. It also changes the target for these test cases to pwr10. Reviewed By: #powerpc, nemanjai Differential Revision: https://reviews.llvm.org/D109126

Commit 5a6dfb27ca7424f15a20f9bb7ec90d858865faa3 by mkazantsev [IndVars] Replace PHIs if loop exits on 1st iteration This is a part of D108910. We replace all loop PHIs with values coming from the loop preheader if we proved that backedge is never taken. Patch by Dmitry Makogon!

Commit d9ca444835e67960df927d5b8cade57776fdd8cb by mkazantsev [IndVars] Break backedge and replace PHIs if loop exits on 1st iteration Implement TODO in optimizeLoopExits. Now if we have proved that some loop exit is taken on 1st iteration, we make all branches in the following exiting blocks always branch out of the loop and their conditions simplified away.
