Vincent Zhao 654e8aadfd [MLIR] Consider AffineIfOp when getting the index set of an Op wrapped in nested loops ... This diff attempts to resolve the TODO in `getOpIndexSet` (formerly known as `getInstIndexSet`), which states "Add support to handle IfInsts surronding `op`". Major changes in this diff: 1. Overload `getIndexSet`. The overloaded version considers both `AffineForOp` and `AffineIfOp`. 2. The `getInstIndexSet` is updated accordingly: its name is changed to `getOpIndexSet` and its implementation is based on a new API `getIVs` instead of `getLoopIVs`. 3. Add `addAffineIfOpDomain` to `FlatAffineConstraints`, which extracts new constraints from the integer set of `AffineIfOp` and merges it to the current constraint system. 4. Update how a `Value` is determined as dim or symbol for `ValuePositionMap` in `buildDimAndSymbolPositionMaps`. Differential Revision: https://reviews.llvm.org/D84698		2020-08-09 03:16:03 +05:30
