68e9721aa8 Rename Deaffinator to LowerAffineApply and patch it.
Several things were suggested in post-submission reviews.  In particular, use
pointers in function interfaces instead of references (still use references
internally).  Clarify the behavior of the pass in presence of MLFunctions.

615c41c788 Introduce Deaffinator pass.
This function pass replaces affine_apply operations in CFG functions with
sequences of primitive arithmetic instructions that form the affine map.

The actual replacement functionality is located in LoweringUtils as a
standalone function operating on an individual affine_apply operation and
inserting the result at the location of the original operation.  It is expected
to be useful for other, target-specific lowering passes that may start at
MLFunction level that Deaffinator does not support.
