  [AArch64] Disable aarch64-enable-gep-opt

This option was enabled in D128582, and whilst it seems to be a net
improvement in many cases, at least a couple of issues have been
reported from D135957 and from the CSE added to the backend causing more
instructions in executed blocks. Revert for the time being, until we can
improve the precision.
