ScopInfo: Use getArrayAccessFor in reduction detection
Load instructions may possibly be related to multiple memory accesses, but we
are only interested in the array read access that describes the memory location
the load instructions loads from. By using getArrayAccessfor we ensure to always
obtain the right memory access.
This issue was found by inspection without having a failing test case.
