clang-p2996/llvm/test/Analysis/DependenceAnalysis/Coupled.ll
David Green d143c65de3 [DA] Enable -da-delinearize by default 
This enables da-delinearize in Dependence Analysis for delinearizing array
accesses into multiple dimensions. This can help to increase the power of
Dependence analysis on multi-dimensional arrays and prevent having to fall
back to the slower and less accurate MIV tests. It adds static checks on the
bounds of the arrays to ensure that one dimension doesn't overflow into
another, and brings our code in line with our tests.
