  [MLIR][LLVM][SROA] Avoid splitting dynamically indexed allocas (#85758)

This commit ensures that SROA does no longer attempt to split allocas
that are indexed into dynamically. Dynamic indices into arrays are
allowed to be negative or out-of-bounds, when the alloca containing the
array has memory backing these produced indices.
