Francis Visoiu Mistrih d7eebd6d83 [CodeGen][NFC] Make TII::getMemOpBaseImmOfs return a base operand ...

Currently, instructions doing memory accesses through a base operand that is
not a register can not be analyzed using `TII::getMemOpBaseRegImmOfs`.

This means that functions such as `TII::shouldClusterMemOps` will bail
out on instructions using an FI as a base instead of a register.

The goal of this patch is to refactor all this to return a base
operand instead of a base register.

Then in a separate patch, I will add FI support to the mem op clustering
in the MachineScheduler.
