[PATCH] D34220: [AArch64] Prefer B.cond to CBZ/CBNZ/TBZ/TBNZ when NZCV flags can be set for "free"

[Andrew Pinski via Phabricator via llvm-commits]

apinski-cavium added a comment.

Note this should be an improvement for ThunderX (though maybe it is not modeled correctly).  Not ThunderX2T99 though (only because fusion happens even for add/cbz cases too).
