MSVC has trouble resolving the static 'printOptionValue' from the method on llvm::cl::opt/list. This change renames the static method to avoid this conflict. PiperOrigin-RevId: 286978351

There was a problem hiding this comment.
Actually, enumerate is useless here, the body of the loop never accesses indexedStride.value(). Could you just rewrite the loop to iterate on index to remove the confusion that led to the bug in the first place?

The computation of dynamic strides in lowering AllocOp was wrong.
Given a MemRefType with
sizes = [5, 10], it computedstrides = [5, 1], while the correct answer should bestrides = [10, 1].
