  Log Message:
  -----------
  [AArch64] Add option to enable/disable load-store renaming.

This patch adds a new option to enable/disable register renaming in the
load-store optimizer. Defaults to disabled, as there is a potential
mis-compile caused by this.

(cherry picked from commit 8e3f59b45ae185cc9b4e3a817d7ac958f1d55976)
