[PATCH] D21571: [AArch64] Avoid generating indexed vector instructions for Exynos

[Abderrazek Zaafrani via llvm-commits]

az updated this revision to Diff 72920.
az added a comment.

Added a simple check to exit this pass early on so that no analysis is done for targets that do not need it. 
Since there was a push against adding any target feature when this patch was first introduced, the check is mainly comparing the latency of indexed fmla with its replacement.
