[PATCH] D39914: [AArch64][Falkor] Rewrite DestReg to avoid tag collision

[Jun Bum Lim via Phabricator via llvm-commits]

When rewritting loads to avoid tag collision, we first try to rename DestReg.
If DestReg cannot be rewritten, then we continue trying to rewrite BaseReg.
Test cases should be added soon.
