  [ScalarEvolution] Control flag for nonstrict inequalities in finite loops

D118090 causes a pretty significant (19%) regression in some Eigen
benchmarks. Investigating is a bit time consuming as the compilation
unit where this occurs is large. Rather than revert, this patch adds a
flag controlling that behavior (enabled by default).
