[SystemZ] Use VT (not ArgVT) for SlotVT in LowerCall(). (#82475)
When an integer argument is promoted and *not* split (like i72 -> i128 on
a new machine with vector support), the SlotVT should be i128, which is
stored in VT - not ArgVT.
Fixes #81417
(cherry picked from commit 9c0e45d7f0e2202e16dbd9a7b9f462e2bcb741ae)
