Summary: Currently the dependence analysis in LLVM is unable to compute accurate dependence vectors for multi-dimensional fixed size arrays. This is mainly because the delinearization algorithm in scalar evolution relies on parametric terms to be present in the access functions. In the case of fixed size arrays such parametric terms are not present, but we can use the indexes from GEP instructions to recover the subscripts for each dimension of the arrays. This patch adds this ability under the existing option `-da-disable-delinearization-checks`.
