[AArch64][SVE] Fix the indexed addressing mode when FI = 0.
This is an alternative fix to D145497, which also addresses
https://github.com/llvm/llvm-project/issues/60918
In D124457 which added the original code for this, @efriedma pointed
out that it wasn't safe to assume that FI #0 would be allocated at offset
0, but that part of the patch went in without any changes.
The downside of this solution is that any access to an object on the
stack that has been allocated at SP + 0, still gets moved to a separate
register first, which degrades performance.
