This is a fix for PR50481 Immediate values for AddrModeT2_i8s4 are already scaled in MCinst operand. This patch changes the number of bits and scale factor to reflect that state when checking stack offset status. AddrModeT2_i7s[2|4] also have this particularity but since MVE instructions are not outlined, just move these cases to the unhandled ones. Differential Revision: https://reviews.llvm.org/D103167
