Minimal Fix for the incorrect rangecheck elimination issue reported by Mike Danes

RangeCheck::IsBinOpMonotonicallyIncreasing has a bug that results in incorrect range check elimination – when the second operand is a lclvar it does not check if it’s a positive value, it only checks if it’s monotonically increasing and any constant is treated as such.
