Revert "[AArch64][GlobalISel] Don't contract cross-bank copies into truncating stores."

This reverts commit 67bf3ac7446bd8ba16bb5ef82fa9f28a848616da.

The reason is that this change is now superseded by 04fb9b729a53 which fixes the
underlying problem in the selector. Now it's fine to generate truncating FP stores
since the selector code will just generate subreg copies to handle them.
