The only benefit of FunctionPass is that it filters out function
declarations. This isn't enough to justify carrying it around, as we can
simplify filter out declarations when necessary within the pass. We can
also explore with better scheduling primitives to filter out declarations
at the pipeline level in the future.
The definition of FunctionPass is left intact for now to allow time for downstream
users to migrate.

NFC. Move out and expose affine scalar replacement utility through
affine utils. Renaming misleading forwardStoreToLoad ->
affineScalarReplace. Update a stale doc comment.

* Extract "value" functionality of `FlatAffineConstraints` into a new derived `FlatAffineValueConstraints` class. Current users of `FlatAffineConstraints` can use `FlatAffineValueConstraints` without additional code changes, thus NFC.
* `FlatAffineConstraints` no longer associates dimensions with SSA Values. All functionality that requires this, is moved to `FlatAffineValueConstraints`.
* `FlatAffineConstraints` no longer makes assumptions about where Values associated with dimensions are coming from.

Deduce circumstances where an affine load could not possibly be read by an operation (such as an affine load), and if so, eliminate the load

MemRefDataFlow performs mem2reg style operations for affine load/stores. Unfortunately, it is not presently correct in the presence of external operations such as memref.cast, or function calls. This diff extends the functionality of the pass to remain correct in the presence of such ops.

Make store to load fwd condition for -memref-dataflow-opt less
conservative. Post dominance info is not really needed. Add additional
check for common cases.
