Matrix has been templated to Matrix (for MPInt and Fraction) with
explicit instantiation for both these types.
IntMatrix, inheriting from Matrix<MPInt>, has been created to allow for
integer-only methods.
makeMatrix has been duplicated to makeIntMatrix and makeFracMatrix.
This was already landed previously but was reverted in
98c994c8e22d7f38cc04f56ee5cdeb337734414d due to build failure. This
fixes the failure.
The method implementations remain in the .cpp file; explicit instantiations have been added for these two types.
makeMatrix has been duplicated to makeIntMatrix and makeFracMatrix.
Fix a bug in detecting unknown ids as mods of known ids that was
preventing certain fusions.
While at this, fix the function signature of `detectAsMod` function to
have output as the last argument.

`BoundType` is no longer a nested member of `IntegerRelation` but a top-level enum in the `presburger` namespace.
This allows `BoundType` to be predeclared in header files. Nested members cannot be predeclared.

The new class hierarchy is as follows:
* `IntegerRelation` (no change)
* `IntegerPolyhedron` (no change)
* `FlatLinearConstraints`: provides an AffineExpr-based API
* `FlatLinearValueConstraints`: stores an additional mapping of non-local vars to SSA values
* `FlatAffineValueConstraints`: provides additional helper functions for Affine dialect ops
* `FlatAffineRelation` (no change)
`FlatConstraints` and `FlatValueConstraints` are moved from `MLIRAffineAnalysis` to `MLIRAnalysis` and can be used without depending on the Affine dialect.
This change is in preparation of D145681, which adds an MLIR interface that depends on `FlatConstraints` (and cannot depend on the Affine dialect or any other dialect).
