[SystemZ] Improve getMemoryOpCost() to find foldable loads that are converted. 

The SystemZ backend can do arithmetic of memory by loading and then extending
one of the operands. Similarly, a load + truncate can be folded into an
operand.

This patch improves the SystemZ TTI cost function to recognize this.
