Existing reduction detection algorithm does two types of memory checks before marking a load store pair as reduction. Second check is to verify there is no other memory access in ScopStmt overlapping with the memory of load and store that forms the reduction. Existing check misses cases where there could be probable overlap such as A[V] += A[P]; In the above case there is chance of overlap between A[V] and A[P] which is missed. This commit addresses this by removing the parameter from space before checking for compatible space. Part 1 of this patch : [75297](https://github.com/llvm/llvm-project/pull/75297)
