Tilmann Scheller 47e3b43768 [AArch64] Add a regression test for the load store optimizer.
We have a couple of regression tests for load/store pairing, but (to my knowledge) there are no regression tests for the load/store + add/sub folding.

As a first step towards increased test coverage of this area, this commit adds a test for one instance of a load + add to pre-indexed load transformation.
