In PR88834, IVOPT is not selecting the right addressing mode. Inorder to fix thix,
we need to add support to add IV uses for IFN_MASK_LOAD_LANES and IFN_MASK_STORE_LANES.
In addition, we also need to add IV candidate with scaled by the element or access size if
that is useful. Richard Sandiford has provided some feedback in the PR and I tried to
incoporate this in PATCH1.

PATCH 2 is the changes needed in aarch64 back in the testadjustments.

Bootstrap and regression testing for the current version is ongoing.

Thanks,
Kugan
