Tilmann Scheller cc3ebc8a98 [AArch64] Add store + add folding regression tests for the load/store optimization pass. 
Add tests for the following transform:

 str X, [x0, #32]
  ...
 add x0, x0, #32
  ->
 str X, [x0, #32]!

with X being either w1, x1, s0, d0 or q0.

Tilmann Scheller 2d746bcda3 [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.
